INTRODUCTION

The LS-6 and LS-8 LightSwitch® Telescopes

The most sophisticated and easiest to use telescopes ever

Congratulations on receiving your new LS telescope. You’ll ﬁ nd that this telescope system has all you need to explore the Universe we live in. Meade’s concept was to create a telescope that would be simple enough for anyone to use, yet capable enough for the experienced amateur to stretch their knowledge and skills. With the most advanced and complete list of features of any telescope, you will have plenty of room to learn and expand your interest in astronomy and not out grow your telescope. Here are a few of the features that set the Meade LS telescope system apart from all others.

Ease of Use: LightSwitch Technology is the ultimate in easy setup. Using a combination of optical, mechanical

and electronic sensors, LightSwitch delivers a telescope ready to start observations without any input from the user.

Optics: Your choice of optical systems to meet your needs. Meade’s Schmidt-Cassegrain (SC) optics

give you high performance for the best possible price. Water-white glass, Ultra-High Transmission Coatings (UHTC) and oversized, thermally-stable Pyrex® primary mirrors provide spectacular viewing experience not available on comparable competitors’ telescopes. Advanced Coma-Free takes all of the features of our SC models and then ups the ante. ACF gives a ﬂ atter , coma-free ﬁ eld of view with pinpoint images all the way to the edge of the ﬁ eld, equaling Ritchey-Crétien performance. ACF is the perfect solution for the serious astroimager or visual astronomer looking for observatory-class optics.

Mechanics: Strong and stable aluminum castings with large precision worm-gear drives in both axes for smooth

tracking with low periodic error.

Computer: AutoStar III handbox gives you complete control of your LS system from the palm of your hand.

With a database of nearly 100,000 objects, you will never run out of things to explore.

Multimedia: The Astronomer Inside™ provides audio and video descriptions of the objects you are viewing

with a wealth of information along with guided tours of the best objects in your sky.

Imaging: The built-in ECLIPS™ CCD Module enables you to take wide-ﬁ eld digital images of the sky, view

them real time with an attached video monitor and save them to an SD card without using and external computer.

If you are like us, you can’t wait to get outside under a dark sky to try out your new LS telescope. We have provided a Getting Started Guide that will get you up and running in the shortest amount of time possible. After your ﬁ rst experience, please sit down with this manual and read about all the advanced features that are available to you with this telescope system. We are conﬁ dent that the LS will keep you fascinated with the Universe and entertained for many years to come.

Clear Skies,

The people at Meade

INDEX

GETTING STARTED

You may want to perform the LS assembly indoors in the light so that you become familiar with the parts and operation before moving the telescope outside into the dark for observing. This Getting Started Guide assumes you are too impatient to read the entire manual ﬁ rst and want to use your new telescope as quickly as possible. Just follow the simple steps below and you will be up and running before you know it.

 It is best to set up the telescope in twilight or before

sunset the ﬁ rst time you use it. Take the telescope and tripod outside. Set the telescope in a large open area where you can see lots of sky. Don’t setup right next to a building or a wall. Also try to stay away from large metal objects like a car or a metal fence. Make sure the ground is stable and is approximately level. It is best to set up the scope away from bright nighttime lighting. Bright lights will spoil your night vision and impede your ability to see the sky. Additionally, it will take the telescope longer to align itself if there are too many bright lights around.

Lock-Knob

GETTING STARTED

Assembling the Tripod

 Remove the ﬁ eld tripod from the shipping carton.

Stand the tripod vertically with the tripod feet down and with the tripod still fully collapsed. Grasp two of the tripod legs and, with the full weight of the tripod on the third leg, gently pull the legs apart to a fully open position.

 Thread in two lock-knobs on each leg (six total)

near the foot of each tripod leg. Use the lock-knobs to vary the height of the inner, extendible tripod leg sections. Tighten the locks to a ﬁ rm feel only; do not overtighten.

Spreader Shaft

End Nut

Spreader Bar

 Remove the end nut from the spreader shaft

and slide the spreader in between the telescope legs. Attach the end nut and hand tighten until the telescope legs are held snuggly in the most spread position. Position the tripod where you want the telescope to be and check that the top of the tripod is approximately level.

INDEX

Mounting the Telescope

Center Hub

Follow the battery polarity (orientation) as indicated by molded icons

GETTING STARTED

Thumb-Screw

 Take the LS Telescope from its packaging and

place the entire telescope onto the top of the tripod head. Rotate the telescope head slowly until you feel the scope register on the center hub of the tripod head. Carefully screw the three attachment thumb-screws on the bottom of the plate to the base of the tripod. Hand tighten the screws so the telescope cannot spin or wobble on the tripod head.

Installing the Batteries

CAUTION: Use care to install batteries as indicated by the battery compartment. Follow battery manufacturer’s precautions. Do not install batteries backwards or mix new and used batteries. Do not mix battery types. If these precautions are not followed, batteries may explode, catch ﬁ re, or leak. Improperly installed batteries void your Meade warranty. Always remove the batteries if they will not be used for a long period of time.

Using an AC Adapter or DC Power Cord

Power

Port

 Remove the end cover from the battery

compartment exposing the battery tray. Carefully slide the battery tray out until it reaches its end stop. Insert 8 (user supplied) Alkaline “C” batteries into the battery compartment. Take care that the batteries + and - ends are as indicated in the battery holder.

Slide the battery compartment back into the telescope and re-attach the battery compartment cover.

INDEX

 Use only the optional Meade Universal AC Power

Adapter (part number 07584 for North America or 07584F for 220v foreign) with your LS telescope when connecting to AC power. It is speciﬁ cally selected to provide the quality voltage and current required to power and protect the electronics in the telescope. Power adapters from other manufactures may cause damage and void your warranty.

Plug the AC plug into a household AC socket and the DC plug into the 12v DC jack on the telescope panel.

For external DC power use the optional #607 DC Power Cord (part number 07043) to connect to an automotive 12v DC accessory socket.

Attaching Accessories

Your Telescope is now Fully Assembled

GETTING STARTED

 Now remove the dust cover from the front

of the telescope tube. Be careful not to touch the glass lens.

 Be sure the telescope master power switch is in

the off position. Remove the AutoStar III handbox and the coiled interface cable from the packing materials. Plug one end into the HNDBX port of the control panel and plug the other end into the Handbox port on the AutoStar III handbox.

Rear Cell Thread

 Remove the dust cap from the rear cell of the

telescope. Thread the 1.25" eyepiece holder onto the rear cell thread. Slide the diagonal prism into the eyepiece holder and lock in place by turning the thumbscrew to a ﬁ rm feel. Place the Super Plössl 26mm eyepiece into the diagonal prism and tighten the diagonal prism thumbscrew to a ﬁ rm feel only.

 Next remove the dust cap from the ECLIPS CCD

Module and put it in a safe place.

Powering Up The Telescope

 When night has fallen, approximately 1 hour after

sunset, turn on your telescope. Flip the LightSwitch on the telescope fork arm to the ON (1) position. The copyright message lights on LS’s LCD display.

INDEX

 After the telescope powers on, you will hear a brief

introductory message. Y ou can press the “MEDIA” key to bypass the introduction if you like.

If you have attached a video cable from the Video Out connection on the telescope to the composite video input of a NTSC TV monitor , you will also see graphics accompanying the telescope introduction.

 At the end of this message, the telescope will

immediately start its LightSwitch Automatic Alignment procedure. It will take about ﬁ ve to ten minutes for the telescope to orient and align itself. Once it has completed the alignment the handbox screen will display “Alignment Successful”.

GETTING STARTED

 At this point look through the eyepiece of the

telescope. You should see some light from the ﬁ nal alignment star but it is probably out of focus. Adjust the focus using the knob on the back of the telescope until you get a sharply focused star image.

 Press the “Tours/8” key on the AutoStar and select

the “Tonight’s Best” tour by pressing the Scroll Down arrow key at the bottom of the AutoStar . Press “ENTER” to start the tour of the best objects visible in your sky right now. You will hear a brief introduction to the tour and then the ﬁ rst object will be shown on the second line of the AutoStar display . If you press “ENTER” to select this object, you will hear a description of the object. If you press the GoTo key, the telescope will move (slew) to put the object in the eyepiece so you can view it directly . To move to the next object, press the “BACK” key and then the Scroll Down key to move through the available objects in the tour. Press “ENTER” to select the displayed object. To exit the tour, press the “Mode” key.

LS TIPS

“MODE” Key

The

“MODE” Key cycles the telescope through

its three different modes; Menu Mode, Info Mode and Skymap Mode.

During most telescope operations, pressing the

“MODE” key will stop the current

operation.

INDEX

 When you are ﬁ nished observing for the night,

replace the dust cover over the end of the telescope and the dust cap on the lens of the ECLIPS Module. Select “Shutdown” from the main top level menu. After the telescope has moved to its storage position and the AutoStar displays “Turn Off Telescope”, ﬂ ip the LightSwitch to the OFF (0) position.

AUTOSTAR III HANDBOX – BASIC USAGE

Now that you have successfully setup and used your LS telescope, it’s time for more information about all the capabilities of this amazing optical system.

The ﬁ rst step is to familiarize yourself with the AutoStar III handbox operation. The largest keys on the keypad are the motion control keys. Most of the time, these keys allow you to move, or slew, your telescope both up and down and right and left. Press them now and see how the telescope moves in response to the keys. When the telescope initially starts up the scope is set to move at its fastest speed. While this is great for getting close to the area you want to see, it is really too fast to get anything positioned into the eyepiece. For that reason, the LS has 9 distinct speeds.

To change the telescope’s speed, press the 1/SPEED key. You can now select a speed with the scroll up and down small arrow keys on the bottom of the hand control. When you have the desired speed selected, press the “ENTER” key . Alternatively, when the speed selection screen is showing, you can just press a number 1-9 to select a speed quickly, where 1 is the slowest and 9 is the fastest.

AUTOSTAR III BASIC USAGE

Key Functions

“BACK” - return to previous menu.

“ENTER” - select or conﬁ rm entry. “GO TO” - Slew to currently selected object. “SPEED” - Adjust Slew Speed. “FOCUS” - Optional Electronic focuser. Motion

pad controls focuser. Up/Down scrolls focus speed. “VOL”. - Up/Dn adjusts media volume. “DISP” - Control Display contrast, brightness. “MODE” - Cycles thru Menu -> Scope info -> SkyMap -> Menu and aborts current operation.

“MEDIA” - Toggles media on and off. “CALD” - Lookup Caldwell Objects “MES” - Look up Messier Objects “PLANETS” - Look up planets in our

solar system “STAR” - Look up bright stars

Take a moment and try move the scope around at some different speeds.

Navigating the Menus

Now that you are starting to get comfortable with the basics, lets learn some new keys. The most important keys for navigating the menus on you telescope are the keys along the top and bottom rows of your AutoStar. The two small arrows on the bottom of the key pad, allow you to scroll through the possible menu selections. The menu line is at the top of the handbox display and the top of the video monitor if connected. The second line of the hand control display has the current active menu item. If you are looking at a connected video display , you will see more menu choices and the active selection will be highlighted.

INDEX

The “ENTER” and “BACK” buttons on the top of the display let you move up and down the menu tree. When you press “ENTER” you will select the current active menu choice. Pressing “BACK” will move you up the menu tree. To get us to the top of the menu tree, press “BACK” until “Select Item” is displayed on line 1 of the display. This is the top level menu. Use the scroll keys to navigate through the choices until you ﬁ nd “Objects”. Press “ENTER”. Now you should be able to navigate to “Constellations”. Once you are there press “ENTER” again. Now press “ENTER” to select “Andromeda”.

The telescope will now start to tell you the story of Andromeda. You can listen to the whole story, or press the “MEDIA” key to skip the story and more menu choices will appear. If you want to go from the menu, “BACK” to the story , just press the “MEDIA” key again to restart the story.

A complete tree of the available menu choice is contained in ﬁ gure 6 on page 23 of the manual.

CHANGING MODES

Menu Mode

Shortcuts!

Now lets look at the numeric keypad. Each of the number keys does two things. If the telescope is requesting input, the number keys allow you to enter digits into the telescope. When you are navigating the menus they act as shortcuts. Their assignments are as follows:

1. “SPEED”: We have already used this key. It allows you to change the slew speed of the telescope.

2. “CALDWELL”: Let’s you look up members of a popular group of bright deep sky objects that make up the Caldwell Catalog.

3. “MESSIER”: Let’s you look up some of the most famous bright deep sky objects that make up the Messier Catalog

4. “FOCUS”: If you have the optional electric focuser on you your telescope you can press this key to go to focus mode. Now the arrow keys will move the focus in or out.

5. “PLANETS”: Lets you directly lookup a planet.

AUTOSTAR III BASIC USAGE

Up till now we have been exploring the Menu Mode. The handbox has several other modes in addition to simple menu navigation. You will notice the “0” key is also labelled “MODE”. Pressing “MODE” allows you to cycle through the telescopes three modes.

Scope Info Mode

Press “MODE” now . In Scope Info Mode the scroll keys allow you to look at the current time, date, and location where the telescope is pointing along with other key values about the status of your telescope.

Sky Map Mode

Press “MODE” again. The hand control display will show “Sky Map FOV=45”. In sky map mode an attached video monitor shows a planetarium-like map of the sky in the area where your telescope is pointed. Use the motion keys to move the scope and notice how the sky display changes as you move the scope. You can zoom the display in or out by pressing the scroll up and scroll down buttons.

6. “STARS”: Lets you directly lookup a bright stars.

7. “VOLUME”: Gives you quick access to the

telescope audio volume control

8. “TOURS”: Lets you directly select a guided tour.

(note: to exit a tour at any time hit the

“MODE” Key.)

Now spend a little quality time with the telescope to get comfortable navigating its features. When you a comfortable, it is time to go out and explore the night sky.

LS KEY FEATURES

Because your telescope has so much magniﬁ cation, its ﬁ eld of view is very small. This can make it hard to know exactly where your telescope is pointing by simply looking at it. To help you point the telescope quickly and accurately , for terrestrial targets or when not using Auto Alignment and GO TO pointing, the LS has a 1X Red-Dot Viewﬁ nder.

The Red-Dot Finder will aid you in pointing your telescope easily. It works much like a ﬁ ghter pilot’s heads-up display. To turn on the Red Dot Finder, carefully rotate the power switch until you feel it click on. Turning further clockwise will increase the dot brightness. Adjust the dot to the minimum brightness where it can be easily seen. This will extend its battery life and make it easier to see faint stars in the background. Look through the ﬁ nder ’s glass window. You will see a red dot superimposed on your view. Using the direction keys on the handbox, move the telescope until the red dot is on the target you want to view in the eyepiece. As you get close to your target, select a moderately low speed, like speed 5, and move the scope to center your target as you look through the eyepiece. This a great way to get used to ﬁ nding the movement keys without removing your eye from the eyepiece.

The Red-Dot Finder has been aligned at the factory, but you may need to touch-up the alignment from time to time. To do this, look through the eyepiece of your scope and using the hand controller center a distant object. Now turn on the Red-Dot Viewﬁ nder and adjust the brightness so you can see the red dot. Look through the sight as pictured above.

Adjustment

Screws

Now, without moving the telescope, adjust the indicated thumb screws until you have put the red dot on the object at which you were looking. It’s that simple.

Now use the hand controller to put the laser dot on a new target. Check to see that the desired target is in the eyepiece.

OPTIONAL ACCESSORIES

Meade makes a complete line of accessories to enable you to get the most fun and performance from your LS telescope. No matter what you want to accomplish, we have the equipment to help you get there.

Choosing Eyepieces

A telescope’ s eyepiece magniﬁ es the image formed by the telescope’s main optics. Each eyepiece has a focal length, expressed in millimeters, or “mm.” The smaller the focal length, the higher the magniﬁ cation. For example, an eyepiece with a focal length of 9mm has a higher magniﬁ cation than an eyepiece with a focal length of 26mm. Experienced users know that higher powers are, in general, not as useful as lower powers. Many of the objects in the night sky are relatively large and faint and look best at low magniﬁ cations.

The power or magniﬁ cation of a telescope is determined by the focal length of the telescope and the focal length of the eyepiece being used. To calculate magniﬁ cation, divide the telescope’s focal length by the eyepiece’s focal length. For example, a 26mm eyepiece is supplied with the LS. The focal length of the 6" LS is 1524mm (see SPECIFICATIONS, page 40).

(just a little less than 1 degree) ﬁ eld of view with 59x magniﬁ cation. This is a very good all purpose eyepiece for your telescope, but you should consider buying additional eyepieces in longer and shorter focal lengths to fully realize the potential of the excellent 6" optical system in your LS telescope.

The Series 4000 Super Plössl Eyepieces are excellent

OPTIONAL ACCESSORIES

Telescope Focal Length 1524mm Eyepiece Focal Length 26mm 1524 ÷ 26 = 58.6x The magniﬁ cation is therefore 58.6x. Low power eyepieces offer a wider ﬁ eld of view, bright,

high-contrast images, and long eye relief. To ﬁ nd an object with a telescope, always start with a lower power eyepiece such as the Super Plössl 26mm or longer focal length. When the object is located and centered in the eyepiece, you may wish to switch to a higher power eyepiece to enlarge the image as much as practical for prevailing seeing conditions or, for many objects, the view is best with a high quality low-power wide-ﬁ eld eyepiece.

NOTE: Seeing conditions vary widely from night-tonight and site-to-site. Turbulence in the air, even on an apparently clear night, can distort images. If an image appears fuzzy and ill-deﬁ ned, reduce to a lower power eyepiece.

Your telescope comes supplied with a Super Plössl 26mm eyepiece, which gives a wide 53 ARC Minute

well corrected 4 element optics at popular prices. They come in a wide range of focal lengths to give you the right magniﬁ cation for any type of celestial object you are viewing. You can also use one of the Series 4000 Barlows to double or triple the magniﬁ cation of a Super Plössl eyepiece. These eyepieces have been the standard for over 30 years.

LS TIPS

Observing Considerations

• Try to pick an observing site away from street and house lights and car headlights. While this is not always possible, the darker the site, the better.

• Try not to use a standard ﬂ ashlight. Experienced observers use red LED ﬂ ashlights, the red utility light on the AutoStar III handbox, or tape red cellophane over their ﬂ ashlights to use for setup and map reading so they don’t have to continually readjust their eyes to the darkness. Be careful not to shine bright lights if there are other observers in the area. Do not shine a ﬂ ashlight into the telescope while someone is observing!

• Dress warmly. It gets chilly when you’re sitting for prolonged periods.

Guided Tour Menu

When Guided Tours is selected, AutoStar III shows you a list of theme tours that will help you explore the night sky . These tours are pre programmed presentations of objects that are visible for the user’s particular location, time and date.

The most popular tour is “Tonight’s Best” that guides the user to the best objects that are currently up in the night sky. This tour is the easiest way to get started exploring the cosmos with your new LS telescope.

Each tour will select the objects, present multi-media clips about the object and, if you press “GoTo”, put that object in the eyepiece of the telescope for you to view.

To exit a tour, press “Mode”. The telescope comes pre-loaded with:

• “Tonight’s Best”, a selection of the most interesting objects visible on any night.

• “A Star’s Life”, explains how stars are formed, created, changes through their lives and ﬁ nally die using examples that are visible tonight.

• “How Far is Far”, an explanation of the phenomenal distances you can see with your LS.

AutoStar Suite also allows you to create your own guided tours of the skies, including your own objects, titles, images and sound ﬁ les (for complete instructions on how to use the authoring tools please refer to the reference manual included on the AutoStar Suite DVD).

Object Menu

Almost all observing with LS is performed using the Object menu category. (NOTE: Exceptions include Guided Tour and Landmarks).

Many LS menu categories contain databases. An LS database is a list of objects, such as stars, planets, comets, nebulae and so forth. When one of these objects is selected from a database by pressing “ENTER” and then “GO TO”, LS moves your telescope (when properly aligned) and points it at the selected object.

The Object Menu options include:

Constellation is a database of all 88 Northern and Southern Hemisphere constellations. When this menu option is chosen and a constellation name appears on the ﬁ rst line of the screen, the multimedia description of the constellation is played. When the media presentation completes, or you press the “MEDIA” key to halt the presentation, a menu gives you three choices:

• Show Summary – presents the key data about the constellation.

• Walk the Stars – presents a catalog of the brightest stars in the constellation so that you can walk the constellation ﬁ gure.

• Show Objects – presents a list of the best deep sky objects in this constellation for you to explore.

Deep Sky is a database of objects outside our Solar System such as nebulae, star clusters, galaxies, and quasars grouped in various catalogs like Messier, Caldwell and NGC.

Star is a database of stars listed in different categories such as named, double, variable, or nearby.

Important Note: When you are looking at descriptive object text, pressing “ENTER” will synchronize the telescope’s coordinates with the object. This is most useful when synching on bright stars to achieve better pointing in the vicinity of the star.

User Catalogs allows the user to deﬁ ne and store in memory deep-sky objects of speciﬁ c interest that are not currently in the LS database. See Appendix B, page 37 for more information (for complete instructions on how to use the authoring tools please refer to the reference manual included on the AutoStar Suite DVD).

Satellite is a database of Earth-orbiting objects such as the International Space Station (ISS), the Hubble Space Telescope (HST), Global Positioning System (GPS) satellites, and geosynchronous orbit satellites. In order to ﬁ nd and track satellites, you must download recent orbital data into the telescope.

Landmarks stores the location of terrestrial points of interest that you create in the permanent LS database.

AUTOSTAR III MENU OPTIONS

Solar System is a database of the eight planets (Earth is not included) in ascending orbits from the Sun, followed by the Moon, asteroids, and comets.

IMPORTANT NOTE: To use the Landmark function, the telescope must be located and aligned exactly as

when the landmark was added to the database.

• Select – To select a Landmark already in the database (see ADD below), choose the “Select” option and scroll through the list. Press “ENTER” to select a Landmark, then press “GO TO” and the telescope slews to the object.

• Add – To add a Landmark, choose the “Add” option. Enter a name for the Landmark. Locate and center the Landmark in the eyepiece, then press “ENTER”.

Event Menu

The Event menu provides access to dates and times of astronomical events. The Event database includes:

Sunrise and Sunset calculates the time that the Sun rises or sets on the current date.

Moonrise and Moonset calculates the time that the Moon rises or sets on the current date.

Moon Phases displays the date and time of the next New, 1st Quarter, Full and 3rd Quarter Moon.

+3.4 halfway through the eclipse as the second star is hidden. LS calculates minimum magnitude time at mid-eclipse.

Autumn and Vernal Equinox calculates the time and date of the fall or spring equinox of the current year.

Winter and Summer Solstice calculates the time and date of the winter or summer solstice of the current year.

Park Scope is designed for a telescope that has not moved between observing sessions. Align the telescope one time, then use this function to park the telescope. Next time it is powered up, no alignment is required. Pressing “ENTER” causes the telescope to move to its pre-determined Park position. Once parked, the screen prompts to turn off power.

IMPORTANT NOTE: When the “Park Scope” option is chosen and the display prompts you to turn off the telescope’s power, LS is unable to be returned to operation without turning the power off and then back on.

Setup Menu

The Setup menu’s primary function is to align the telescope. However, there are numerous other features available within the Setup menu, including:

Align prepares your telescope to automatically locate and track objects. There are four different alignment methods available. Unless you speciﬁ cally disable LightSwitch as the default alignment, the scope will use this method immediately upon powering up. If you desire to use an alternate method below, be sure to disable automatic alignment in the preferences.

• Automatic Align will use the LightSwitch alignment method to align your telescope.

• Alt. Az. 2 Star will begin the interactive two star alignment process. Complete details are described in the Advanced LS features section of this manual.

• Alt. Az. 1 Star will begin the interactive one star alignment process. Complete details are described in the Advanced LS features section of this manual.

• Terrestrial will set up the telescope to use on land objects.

Preferences allows you to conﬁ gure the telescope’s behaviors to suit your own viewing tastes. Conﬁ gurable options include:

• Restore Defaults sets all the settings back to the factory original values.

• Hi Precision Slews allows you to turn high precision slews on and off. When this feature is enabled and you command the telescope to GoTo and object, it will ﬁ rst slew to a nearby star and ask you to center the star and then press “ENTER” to proceed. This feature insures the target will be in the precise center of the eyepiece. With faint objects at the limit of your scope, or when making astro-images, enabling Hi Precision assures you are right on target.

• Default Alignment allows you to enable or disable LightSwitch alignment when the scope powers up. When you disable default alignment, the telescope will require you to select and perform one of the alignment procedures under the Setup menu before your telescope will automatically locate and track objects.

• Play Intro Video allows you to disable the introductory media message that plays when the telescope is ﬁ rst powered up.

• Play Media 1

multimedia object descriptions are played. As shipped from the factory, the telescope is conﬁ gured to play the descriptive media before showing you the object data. Disabling the Media 1st option, will cause the object’s data to be displayed immediately upon object selection. If you wish to hear the descriptions, you must explicitly press the “MEDIA” key.

• Animated Media allows you to bypass the animated portion of the media. As shipped from the factory, most objects have two media clips. The ﬁ rst is an animated overview narrated by a male voice. This is followed by a second, more detailed description given by a female narrator. Disabling “Animated Media” will skip playing the audio/video media clip and go to the audio only presentation.

• Time Zone allows you to select an international time zone, or to manually conﬁ gure a time zone to any fraction of an hour you need.

• Use GPS allows you to disable use of the GPS to determine the time and your telescope’s location. If your scope is mounted in an

When the GPS is disabled, you are presented a menu that offers you the choice of using the previous locations, and the internal clock time, entering the date, time and location manually, taking a GPS ﬁ x, or starting in a Demo/Terrestrial mode.

• Rev. N/S allows you to reverse the function of the up and down arrow keys. This can be handy when using diagonals.

• Rev. E/W allows you to reverse the function of the left and right arrow keys. This can be handy when using diagonals.

• Parking Place allows you to set a custom park position. This is convenient for permanently mounted scopes that will be restarted and parked after every use.

• Custom Rate allows you to make minor adjustments to the telescopes tracking rate.

Tip: If you are having difﬁ culties with the telescope, the ﬁ rst step to getting back on track is to use the Preferences – Restore Factory Defaults command rate.

Calibrate allows you to precisely tune several aspects of your telescope for peak performance. Calibration options include:

• Azimuth Drive allows you train your azimuth drive for peak pointing accuracy.

• Elevation Drive allows you train your elevation drive for peak pointing accuracy.

• Finder Center recomputes the center of the ECLIPS camera. When you change diagonals or other equipment the alignment of the equipment with the ECLIPS camera can change. If you are getting good alignments, but objects are consistently off center by the same amount, you should use the option to improve centering.

ADVANCED LS FEATURES

T wo Star Alt Az Alignment

1. Select Alt. Az. 2 Star alignment from the Align

menu to begin two star alignment.

2. “Automatic Alignment” displays. The system now performs the following routines (press any ETX LS key to abort Automatic Alignment).

Caution: As the telescope performs the following operations, it will swing and rotate. Keep a safe distance from the telescope. The telescope now ﬁ nds the level and tilt position of the telescope, and also detects where true North is. It may not actually level or tilt the telescope or point to North — it is just detecting these positions. This may take a minute or two.

e. “Automatic Alignment: Selecting Star” and

“Slewing” display. When it is close to the alignment star “Center Brightest Star: Press “ENTER”” displays. When the telescope slews to the ﬁ rst star, it may not appear in the ﬁ eld of view in the eyepiece. Use the Red Dot Finder (Pg. 12, Fig. 2, 16) to locate the star. The alignment star will be easy to recognize — it will be the brightest star in the area of the sky where the telescope is pointing. Use the Arrow keys to center the alignment star in the eyepiece. When the alignment star is centered, press “ENTER”. Repeat the procedure for the second alignment.

ADVANCED LS FEATURES

a. Attempts a “GPS Fix”. The GPS receiver

attempts to acquire and sync up with signals from GPS satellite system. “Getting GPS Fix” displays Note: Press Mode key to abort the GPS ﬁ x. You will then be prompted to enter the time, date and location.

b. Detects “level” of the base of the telescope;

ﬁ nds tilt and tip. To detect level, LS must calculate “level” at three compass points. LS also determines the positioning (i.e., tilt and tip) of the optical tube.

c. Finds North. Locates magnetic North, then

calculates true North.

NOTE: After performing these operations, LS now knows:

• The telescope’s limiting positions

• Where level is for the telescope

• The location of true North

• The observing site’s location

• The date and time

d. Once the level, tilt and North are detected,

the telescope will “GO TO” 2 alignment stars. The telescope will go to these stars in order to orient itself to the sky. Once it has done this, it will be able to point to any one of nearly 100,00 objects in its database.

f. The telescope now slews to the second alignment star. LS displays “Center Brightest Star”.

g. “Press “ENTER”” displays. Use the Arrow keys to center the alignment star in the eyepiece. When the second alignment star is centered, press “ENTER”.

h. “Alignment successful” displays. If “Alignment

Unsuccessful” displays, perform the procedure again.

NOTE: If you have an obstruction, such as a tree or a building blocking your view of the alignment star, or if you have any doubts at all about the star that has been chosen, no problem. Just press the SCROLL DOWN key and LS will ﬁ nd another star to align upon.

NOTE: The selected alignment stars may vary by date and time. All that is required is for the observer to center the selected stars in the eyepiece when prompted.

IMPORT ANT NOTE: The “T elescope: Mount” option of the Setup menu is set to “Alt/Az” as the default alignment by the factory. The example presented in this section assumes that you are performing an alignment procedure for the ﬁ rst time with your telescope and therefore, the “Telescope: Mount” option does not need to be selected.

INDEX

Alt/Az 1 Star Alignment

Landmarks

One-Star Alignment requires some knowledge of the night sky . LS provides a library of bright stars. One-Star Alignment is identical to Two-Star Alt/Az: Alignment (see TWO-STAR AL T/AZ ALIGNMENT above), except only one star from the database is chosen by the observer for alignment.

Finding Objects Not in the Database

Although LS contains an extensive database of celestial objects (stars, nebulae, planets, etc.) that you can observe, you may eventually want to view objects that are not part of the database. LS provides a feature that allows you to enter an object’s R.A. and Dec. and allows automatic slewing of the telescope to the userentered coordinates.

In order to use this option, you ﬁ rst need to look up the R.A. and Dec. coordinates of the object or objects you wish to observe. Check out the Internet, local library, or bookstore for astronomy books, CD ROMs, or magazines (such as Sky & Telescope or Astronomy), to ﬁ nd coordinates of celestial objects.

To enter coordinates of an object into the Telescope:

1. Make sure LS has been initialized and the

telescope has been aligned.

2. From any menu press the “MODE” key to change to Scope Info mode.

3. Scroll the display until the telescopes Current RA is displayed.

4. Press the “GO TO” key. The scope will now prompt you to enter the object’s coordinates.

5. “Right Asc.: 00.00.0” displays. Use the Number keys to enter the digits for the Right Ascension coordinate of your object. When you are ﬁ nished, press “ENTER”.

6. “Declination: +00°.00’” displays. Use the Number keys to enter the digits for the Declination coordinate of your object. If necessary, use the Scroll Keys to change “+” to “-”. When you are ﬁ nished, press “ENTER”.

This menu option allows you to deﬁ ne and store terrestrial objects in the Landmark database. First, a landmark needs to be stored in memory using the “Landmark: Add” option. To view a landmark, use the “Landmark: Select” option.

To add a landmark to the database

In this procedure, you will store the location of terrestrial landmarks in LS’s memory.

1. Set the telescope in the home position, if necessary. Note for future reference where the telescope is located and if you have aligned the telescope, which alignment method is used.

IMPORTANT NOTE: To use the Landmark function, the telescope must be located and aligned exactly as when the landmark) was added to the database.

2. Display the “Setup: Targets” menu option. Chose “Terrestrial” and press “ENTER”. Choosing this option turns off tracking for astronomical objects. Be sure to change this option back to “Astronomical” when you wish to view celestial objects again.

3. Press “BACK” once. “Select Item: Setup” displays.

4. Press the Scroll Down key once and “Select Item: Object” displays. Press “ENTER”. “Object: Solar System” displays.

5. Press the Scroll Up key twice and “Object: Landmarks” displays Press “ENTER”. “Landmark: Select” displays.

6. Press the Scroll Down key once. “Landmark: Add” displays. Press “ENTER”.

7. “Landmark Name” displays. Using Arrow keys, enter a name for the landmark you wish to add to the database. When ﬁ nished, press “ENTER”.

7. The telescope will now slew to your object.

INDEX

8. “Center Landmark. Press “ENTER”” displays. Using only the Arrow keys (do not manually move the telescope), move the telescope to the desired landmark and center the object in the eyepiece. Press “ENTER”. The object is now stored in memory.

9. “Landmark: Add” displays. If you wish to add more landmarks, repeat steps 5 through 7.

To view a landmark in the database

1. Make sure the telescope is located and aligned

exactly as when the desired landmark was entered into memory.

2. Display the “Landmark: Select” menu option. Press “ENTER”.

3. Use the Scroll keys to scroll through the list of objects you have previously entered. When the desired object displays, press “ENTER” to select the object. Use the Scroll keys to scroll through location information about the object, if desired. Press “GO TO” to slew the telescope to the landmark.

4. Press “BACK” to exit.

7. When the alarm goes off, return to the Satellite menu and press a Scroll key until the desired satellite is on the top line of the display.

8. Press “GO TO”, LS slews the telescope to where the satellite should appear. The motor drive stops and a countdown is displayed.

NOTE: If the scheduled appearance position of the satellite is obstructed (i.e., by a building, tree, or hill), press “ENTER” and LS starts to move the telescope along the expected satellite track. When the track clears the obstruction, press “ENTER” again to pause the telescope, then continue with this procedure.

9. With about 20 seconds left on the countdown timer, start watching through the telescope Red Dot Finder (Pg. 12, Fig. 2, 16) for the satellite to enter the ﬁ eld of view.

10. When the satellite enters the viewﬁ nder ﬁ eld of view, press “ENTER”. The telescope starts to track with the satellite.

11. Use the LS Arrow keys to center the object in the viewﬁ nder, then look through the eyepiece to view the object.

ADVANCED LS FEATURES

Observing Satellites

In this procedure, you will prepare your telescope to observe a satellite pass.

1. Navigate to the “Object: Satellite” menu option and press “ENTER”.

2. Use the Scroll keys to scroll through the list of satellites.

3. Select a satellite from list and press “ENTER”.

4. “Calculating...” and then “Tracking...” displays.

If the satellite is going to make a pass, “Located” displays.

5. Use the Scroll keys to display data about the pass: aos — acquisition of signal and los — loss of signal. If you subtract the aos from the los, you can calculate how long the satellite will be visible. Location information also displays.

6. “Alarm” displays after the location information. Press “ENTER” and LS automatically sets the alarm to sound a minute before the satellite’s scheduled appearance. You may return to regular observations until the alarm goes off.

Satellite orbits change and new satellites (including the Space Shuttle) are launched. You can use the AutoStar Updater program approximately once a month to get updated information and instructions on how to download this data to LS. If orbital parameters are more than one month old, the satellite pass may not happen at the time predicted by LS. Downloading requires you use a USB cable to connect the telescope to a PC to update the satellite elements.

NOTE: Satellite observing is an exciting challenge. Most satellites are in low orbit, traveling at approximately 17,500 mph. When visible, they move quickly across the sky and are only in the ﬁ eld of view for a few minutes, requiring LS to slew the telescope rapidly . Best viewing is near sunrise or sunset when the sky is dark. Viewing in the middle of the night can be problematic because the satellite may pass overhead, in the Earth’s shadow .

INDEX

Terrestrial Observing

The LS is an excellent high-resolution, terrestrial (land) telescopes. Viewing terrestrial objects requires looking along the Earth’s surface through heat waves. These heat waves often cause degradation of image quality. Lower power eyepieces, like the Super Plössl 26mm eyepiece, magnify these heat waves less than higher power eyepieces. Therefore, lower power eyepieces provide a steadier, higher quality image. If the image is fuzzy or ill-deﬁ ned, reduce to a lower power eyepiece, where the heat waves do not have such an effect on image quality . Observing in early morning hours, before the ground has built up internal heat, produces better viewing conditions than during late afternoon hours.

If you wish to observe a distant land object, such as a mountain top or a bird, you want to use your telescope in its Terrestrial Observing mode. To start up the telescope in Terrestrial mode:

1. Turn on the telescope.

2. When you hear the introductory audio, press the “MODE” key. The telescope will move to the home position, and when it has stopped “Select Item” will show on the Handbox screen. Use the SCROLL keys to move through the menu to “Align”. Press the “ENTER” key again to setup the “Align” menu. Use the SCROLL keys to move to “Terrestrial” and hit “ENTER”.

3. Move your telescope using the direction arrows on the handbox while looking through the RedDot Finder to put your target in the eyepiece.

4. Focus on the target with the focus knob (pg. 12,

Fig. 2, 9).

LS TIPS

Too Much Power?

Can you ever have too much power? If the type of power you’re referring to is eyepiece magniﬁ cation, yes, you can! The most common mistake of the beginning observer is to “overpower” a telescope by using high magniﬁ cations which the telescope’s aperture and atmospheric conditions cannot reasonably support. Keep in mind that a smaller, but bright and well-resolved image is far superior to one that is larger, but dim and poorly resolved (see Figs. 7a and 7b to the left). Powers above 400X should be employed only under the steadiest atmospheric conditions.

Figs. 7a & 7b: Jupiter; examples of the right amount of magniﬁ cation and too much magniﬁ cation.

INDEX

Most observers should have three or four additional eyepieces to achieve the full range of reasonable magniﬁ cations possible with the LS telescopes. See OPTIONAL ACCESSORIES, page 16.

MAINTENANCE

The LS is a precision optical instrument designed to yield a lifetime of rewarding viewing.

Given the care and respect due any precision instrument, the LS will rarely, if ever, require factory servicing. Maintenance guidelines include:

1. Avoid cleaning the telescope’s optics: a little dust on the front surface of the telescope’s correcting lens causes virtually no degradation of image quality and should not be considered reason to clean the lens.

2. When absolutely necessary, dust on the front lens should be removed with gentle strokes of a camel hair brush or blown off with an ear syringe (available at any pharmacy). DO NOT use a commercial photographic lens cleaner.

3. Organic materials (e.g., ﬁ ngerprints) on the front lens may be removed with a solution of 3 parts distilled water to 1 part isopropyl alcohol. You may also add 1 drop of biodegradable dishwashing soap per pint of solution. Use soft, white facial tissues and make short, gentle strokes. Change tissues often.

4. CAUTION: Do not use scented or lotioned tissues

that can damage the optics.

7. If the LS is not to be used for an extended period, perhaps for one month or more, it is advisable to remove the batteries from the telescope. Batteries left in the telescope for prolonged periods may leak, causing damage to the telescope’s electronic circuitry.

8. Do not leave the LS inside a sealed car on a warm summer day; excessive ambient temperatures can damage the telescope’s internal lubrication and electronic circuitry.

Collimation

The optical collimation (alignment) of any astronomical telescope used for serious purposes is important, but in the case of the Schmidt-Cassegrain design of the LS, such collimation is absolutely essential for good performance. T ake special care to read and understand this section well so that your LS will give you the best optical performance.

As part of ﬁ nal optical testing, every Meade Schmidt- Cassegrain is precisely collimated at the Meade factory before shipment. However, vibrations in shipping can cause the optical system to become misaligned. Realigning the optics is, however, a straightforward process.

MAINTENANCE

5. Do not, for any reason, remove the correcting plate from its machined housing for cleaning or other purposes. You will almost certainly not be able to replace the corrector in its proper rotational orientation and serious degradation of optical performance will result. Meade Instruments assumes no liability for damage incurred to the telescope in this way.

6. If the LS is used outdoors on a humid night, water condensation on the telescope surfaces will probably result. While such condensation does not normally cause any damage to the telescope, it is recommended that the entire telescope be wiped down with a dry cloth before the telescope is packed away. Do not, however, wipe any of the optical surfaces. Rather, simply allow the telescope to sit for some time in the warm indoor air, so that the wet optical surfaces can dry unattended.

To check the collimation of your LS, center a bright star that is overhead, or use a “hot spot” of reﬂ ected Sunlight from a chrome car bumper, with the supplied 26mm eyepiece. Allow the telescope to adjust to the temperature of your observation site before proceeding; temperature differences between the optics and the outside air can cause distortion in the images.

(1) (2) (3)

Figure 8: Collimation

With the star or hot spot centered, de-focus the image.

You will notice that the out of focus star image looks like a ring of light surrounding a dark central spot; the

INDEX

dark central spot is in fact the shadow of the secondary mirror. Turn the focus knob until the ring of light ﬁ lls about 10% of the eyepiece ﬁ eld-diameter. If the dark central spot is offset in (i.e., not concentric with) the ring of light, your telescope’s optical system is misaligned and requires collimation.

Follow these steps for collimation of the optical system:

1. The only adjustments possible, or necessary, on the LS are from the three inner most screws

eyepiece ﬁ eld of view (Fig. 8, 2), in the same direction as the darker shadow is offset in the ring of light.

4. Turn the set screw that you found with the pointing exercise while looking in the eyepiece. You will notice that the star image will move across the ﬁ eld. If while turning the defocused star image ﬂ ies out of the eyepiece ﬁ eld, then you are turning the screw the wrong way. Turn the opposite direction and bring the image back to the center of the ﬁ eld.

MAINTENANCE

Collimation Screws

located at the inner surface of the secondary mirror housing.

CAUTION: Do not force the three collimation screws past their normal travel and do not loosen them more than two full turns in a counterclockwise direction or the secondary mirror may come loose from its support. You will ﬁ nd that the adjustments are very sensitive, usually requiring only one-half turn or less to produce the desired result.

2. While looking at the defocused star image, notice which direction the darker shadow is offset in the ring of light or notice which part of the ring is the thinnest (Pg. 32 Fig. 8, 1). Place your index ﬁ nger in front of the telescope so that it touches one of the collimation set screws. Y ou will see the shadow of your ﬁ nger in the ring of light. Move your ﬁ nger around the edge of the black plastic secondary mirror support until you see the shadow of the ﬁ nger crossing the thinnest part of the ring of light. At this point, look at the front of the telescope where your ﬁ nger is aiming. It will either be pointing directly at a set screw, or it will be between two set screws aiming at the set screw on the far side of the black plastic secondary mirror support. This is the set screw that you will adjust.

5. If the screw you are turning becomes very loose, tighten the other two screws by even amounts. If the screw you are turning gets too tight, un-thread the other two by even amounts.

6. When you bring the image to center (Fig. 8, 3), carefully examine the evenness of the ring

of light (concentricity). If you ﬁ nd that the dark center is still off in the same direction, continue to make the adjustment in the original turning direction. If it is now off in the opposite direction, you have turned too far and you need to turn in the opposite direction. Always double check the image in the center of the ﬁ eld of the eyepiece.

7. You may ﬁ nd after your initial adjustment that the dark center is off in a new direction (e.g., instead of being off side-to-side it is now off in an up-anddown direction). In this case

through 6

8. Now try a higher power eyepiece (e.g., 9mm or less) and repeat the above tests. Any lack of collimation at this point will require only very slight adjustments of the three set screws. You now have good collimation of the optics.

9. As a ﬁ nal check on alignment, examine the star image in focus with the higher power eyepiece as suggested above, under good viewing conditions. The star point should appear as a small central dot (commonly referred to as an “Airy disc”) with a diffraction ring surrounding it. To give a ﬁ nal precision collimation, make extremely slight adjustments of the three set screws, if necessary , to center the Airy disc in the diffraction ring. You now have the best alignment of the optics possible with this telescope.

Inspecting the Optics

A Note About the “Flashlight Test”: If a ﬂ ashlight or

other high-intensity light source is pointed down the main telescope tube, the view (depending upon the observer’s line of sight and the angle of the light) may reveal what appears to be scratches, dark or bright spots, or just generally uneven coatings, giving the appearance of poor quality optics. These effects are only seen when a high intensity light is transmitted through lenses or reﬂ ected off the mirrors, and can be seen on any high quality optical system, including giant research telescopes.

The optical quality of a telescope cannot be judged by the “ﬂ ashlight test;” the true test of optical quality can only be conducted through careful star testing.

Gauging the Movement of the Telescope

A common complaint of many ﬁ rst-time telescope owners is that they cannot see the telescope “move” when the motor drive is engaged. If fact, when the batteries are installed, the power is on, the telescope is moving. However, the movement is at the same speed as the hour hand of a 24-hour clock; as such, the movement is difﬁ cult to discern visually.

To check the movement of your telescope, look at an astronomical object through the telescope’s eyepiece with the telescope polar aligned and with the motor drive on. If the object remains stationary in the ﬁ eld of view, your telescope is operating properly. If not, check to ensure that “Astronomical” is selected in the “Targets” option of the setup menu.

Updating Your LS Firmware

Meade is constantly reﬁ ning and improving the operating ﬁ rmware that controls our computerized telescopes and

we even add new features and capabilities from time to time. Your new LS shipped with the most current ﬁ rmware at the time of manufacture, but there may well be a new version available through the AutoStar Updated program supplied on the AutoStar Suite DVD

supplied with your telescope. The Updater goes online to the Meade web site and checks to see if there is a newer version available and can download it directly to the telescope through a user supplied USB cable or it can create a bootable Mini SD Card that, when inserted into the telescope’s Mini SD Card slot (Pg. 12, Fig. 3, 10), will transfer the ﬁ les to the telescope on startup. Please see the AutoStar Suite documentation for details on how to perform the update.

Here are the steps to update your ﬁ rmware:

1. Install AutoStar Suite software and the USB driver from the DVD included with the telescope.

2. Attached telescope with user supplied USB cable or insert a mini SD card or micro SD in mini holder into a card reader to internet connected computer.

3. Turn on the LS and press “MODE” to abort from the alignment.

4. Run AutoStar Suite

5. Select the “Telescope” menu from the menu bar near the top of the screen.

6. Select “Product Updates” from the drop down menu.

7. Click “OK” or “Yes” in the message box to be sure you have the latest version of the Updater software.

8. If you see “Error Box” about searching for COM Ports and you have your telescope connected with a USB cable, click “Y es”. If you are using an SD Card, click “No”.

9. Click on “Upgrade AutoStar Software Now”.

10. Open the drop down menu called “Specify Type of AutoStar...”.

11. Select LS.

12. If you want to make an Mini SD Card, check the SD box.

13. Click “OK” and the ﬁ rmware will download and install.

BASIC ASTRONOMY

In the early 17th century Italian Scientist Galileo, using a crude telescope considerably smaller than the LS, turned it to look towards the sky instead of distant trees and mountains. What he saw, and what he realized about what he saw, forever changed the way mankind thought of the universe. Imagine what it must have been like being the ﬁ rst human to see moons revolve around the planet Jupiter or to see the changing phases of Venus! Because of his observations, Galileo correctly realized Earth’s movement and position around the Sun, and in doing so, gave birth to modern astronomy . Yet Galileo’s telescope was so crude, he could not clearly make out the rings of Saturn.

Galileo’s discoveries laid the foundation for understanding the motion and nature of the planets, stars, and galaxies. Building on his foundation, Henrietta Leavitt determined how to measure the distance to stars; Edwin Hubble proposed a glimpse into the origin of the universe; Albert Einstein unraveled the relationship of time and light. Almost daily, using sophisticated successors to Galileo’s crude telescope, such as the Hubble Space Telescope, more and more mysteries of the universe are being solved and understood. We are living in a golden age of astronomy.

Unlike other sciences, astronomy welcomes contributions from amateurs. Much of the knowledge we have on subjects such as comets, meteor showers, variable stars, the Moon and our solar system comes from observations made by amateur astronomers. So as you look through your Meade LS telescope, keep Galileo in mind. To him, a telescope was not merely a machine made of glass and metal, but something far more - a window through which the beating heart of the universe might be observed.

Objects in Space

Listed below are some of the many astronomical objects that can be seen with the LS

The Moon is, on average, a distance of 239,000 miles (380,000km) from Earth and is best observed during its crescent or half phase when Sunlight strikes the Moon’s surface at an angle. It casts shadows and adds a sense of depth to the view. No shadows are seen during a full Moon, causing the overly bright Moon to appear ﬂ at and rather

uninteresting through the telescope. Be sure to use a neutral Moon ﬁ lter when observing the Moon. Not only does it protect your eyes from the bright glare of the Moon, but it also helps enhance contrast, providing a more dramatic image.

Using the LS, brilliant detail can be observed on the Moon, including hundreds of lunar craters and maria, described below.

Craters are round meteor impact sites covering most of the Moon’s surface. With no atmosphere on the Moon, no weather conditions exist, so the only erosive force is meteor strikes. Under these conditions, lunar craters can last for millions of years.

Maria (plural for mare) are smooth, dark areas scattered across the lunar surface. These dark areas are large ancient impact basins that were ﬁ lled with lava from the interior of the Moon by the depth and force of a meteor or comet impact.

Twelve Apollo astronauts left their bootprints on the Moon in the late 1960’s and early 1970’s. However, no telescope on Earth is able to see these footprints or any other artifacts. In fact, the smallest lunar features that may be seen with the largest telescope on Earth are about one-half mile across.

BASIC ASTRONOMY

INDEX

Planets change positions in the sky as they orbit around the Sun. To locate the planets on a given day or month, consult a monthly astronomy magazine, such as Sky and Telescope or Astronomy. You can also consult LS for information about planets. Scroll to the “Object: Solar System” menu and scroll through the lists of planets. When a planet you are interested in displays, press “ENTER”. Use the Scroll keys to display information about the planet, such as the planet’s coordinates, and the rise and set times (Tip: enter a date in the Date menu and you can determine if a planet) will be visible during the night of the entered date by checking its rise and set times). Listed below are the best planets for viewing through the LS.

Mars is about half the diameter of Earth, and appears through the telescope as a tiny reddish-orange disk. It may be possible to see a hint of white at one of the planet’s Polar ice caps. Approximately every two years, when Mars is closest to Earth in its orbit, additional detail and coloring on the planet’s surface may be visible.

Jupiter is the largest planet in our solar system and is 1 1 times the diameter of Earth. The planet appears as a disk with dark lines stretching across the surface. These lines are cloud bands in the atmosphere. Four of Jupiter’s 16 moons (Io, Europa, Ganymede, and Callisto) can be seen as “star-like” points of light

when using even the lowest magniﬁ cation. These moons orbit Jupiter so that the number of moons visible on any given night changes as they circle around the giant planet.

Saturn is nine times the diameter of Earth and appears as a small, round disk with rings extending out from either side. In 1610, Galileo, the ﬁ rst person to observe Saturn through a telescope, did not understand that what he was seeing were rings. Instead, he believed that Saturn had “ears.” Saturn’s rings are composed of

billions of ice particles ranging in size from a speck of dust to the size of a house. The major division in Saturn’s rings, called the Cassini Division, is occasionally visible through the LS. Titan, the largest of Saturn’s 18 moons can also be seen as a bright, star-like object near the planet.

Deep-Sky Objects

Star charts can be used to locate constellations, individual stars and deep-sky objects.

Examples of various deep-sky objects are given below:

Stars are large gaseous objects that are selfilluminated by nuclear fusion in their core. Because of their vast distances from our solar system, all stars appear as pinpoints of light, irrespective of the size of the telescope used.

Nebulae are vast interstellar clouds of gas and dust where stars are formed. Most impressive of these is the Great Nebula in Orion (M42), a diffuse nebula that appears as a faint wispy gray cloud. M42 is 1600 light years from Earth.

Open Clusters are loose groupings of young stars, all recently formed from the same diffuse nebula. The Pleiades is an open cluster 410 light years away. Through the LS, numerous stars are visible.
