1.Remove telescope from the carton and Identify all components. READ THROUGH ASSEMBLY INSTRUCTION BEFORE YOU ASSEMBLE YOUR TELESCOPE


• Select one tripod leg and extend the Tripod Leg Middle Section (7). Using the Tripod Leg Lock Screws (10)included in the hardware pack, insert a Tripod Leg Lock Screw into the lower brackets on the Tripod Leg (6). Tighten the Tripod Leg lock Screws so that the Middle Section is securely in place. Repeat for the remaining two legs.

3. Attach Telescope and Finderscope

• Locate the pre-assembled Telescope Main Tube (14)and Altazimuth Yoke Mount (12).

Note: Before assembling tripod legs to Altazimuth Yoke Mount, make sure the Accessory Tray Braces (8) face inward. Locate the long bolts and washers from the hardware pack. Position the mount over the Tripod Leg (6) as shown (fig. 1). and align the holes in the Tripod Leg with the holes in the mount. Insert the bolts through the holes at the top of a Tripod Leg. A washer should be positioned on both outer sides of the Tripod Leg. Attach a wing nut to the bolt, but do not tighten it all the way. Repeat on the remaining two Tripod Legs. Once you have attached all Tripod Legs to the mount, securely tighten all wing nuts. Remove the Stabilizer Bar Mounting Screw (11) from the hardware pack and insert it into the opening at the base of the Vertical Stabilizer Bar (4).

• Locate the Finderscope (1) withpre-assembledmounting bracket. Remove the two nuts located near the front of the telescope (closet to the eyepiece) and place the Finderscope and bracket assembly over the exposed screws. Replace the nuts, and securely tighten the Finderscope and bracket assembly in place.

4. Attach Accessory Tray

• Locate the Accessory Tray (9). Using the accessory tray bolts, wingnuts and washers connect the Accessory Tray to theAccessory Tray Braces (8). Start with one tripod leg and attach wingnuts. Wingnuts should be positioned beneath the accessory tray. Do not tighten wingnuts until all Accessory Tray Braces are attached as some adjustments may be required.

Your Telescope is now ready to be used. To obtain the fullest enjoyment from your telescope,


please refer to the additional following information .


Astronomical telescopes are designed such that the image you see will appear UPSIDE DOWN and REVERSED, this is acceptable for viewing celestial bodies. However, this special telescope offers an Erect Image Eyepiece which will deliver a 30x view that will NOT BE UPSIDE DOWN or REVERSED. This 30x eyepiece is recommended for viewing

either land or night sky based objects.

Using your Eyepieces:

1.You should always start viewing with the lowest power eyepiece, which in this case is the 30x lens. This 30x erect image eyepiece is unique and will correct images to appear right side up as you view them through the telescope. This is especially beneficial when viewing objects on land. Note: While images will not be upside down, they may appear tilted slightly. This apparent tilt is due to your viewing position with relation to the telescope. Depending on where you place your eye, the image tilt will vary. The important feature of this eyepiece is that the image is right side up and correct left to right (not a mirror image).This eyepiece is recommended for either land or sky viewing.

2.The 4mm lens is a traditional telescope eyepiece and will provide an image that on land will very clearly deliver an image that is upside down. However, this is normal and becomes unimportant as you view objects in the night sky. This eyepiece is recommended for sky viewing only.

Focusing Telescope:

1.After selecting the desired Eyepiece (3), aimMain Telescope Tube (14) at aland-basedtarget at least

200yards away (e.g. A telephone pole or building). Fully extend focusing tube by turning Rack and Pinion

Focusing Mechanism (2).

2.While looking through selected Eyepiece (3) (in this case the 30x), slowly retract focusing tube by turning

Rack and Pinion Focusing Mechanism (2) until object comes into focus.

Aligning and Using Red Dot Finderscope:

1.Remove plastic insert on bottom side of finderscope to allow battery to make connection with battery contact for power. Turn power switch on.

2.Look through main telescope tube at low power and establish a well-definedstationary target. Looking through red dot finderscope, alternate tightening each adjustment wheel (at rear and side of finderscope) until the red dot of finderscope is precisely aligned and centered on the same object being viewed in main telescope tube.

Never Look Directly At The Sun With Your Telescope Permanent Damage To Your Eyes May Result.


Enjoying Your New Telescope

1.First determine your targeted object. Any bright object in the night sky is a good starting point. One of the favorite starting points in astronomy is the moon. This is an object sure to please any budding astronomer or experienced veteran. When you have developed proficiency at this level, other objects become good targets. Saturn, Mars, Jupiter, and Venus are good second steps to take.

2.The first thing you need to do after assembling the telescope as planned is center the desired object in the finderscope. Provided you did a reasonable job aligning the finderscope, a quick look through the main telescope tube at low power should reveal the same image. With the lowest power eyepiece (the one with the largest number printed on it) you should be able to focus the same image that you saw through the finderscope. Avoid the temptation to move directly to the highest power. The low power eyepiece will give you a wider field of view, and brighter image--thusmaking it very easy to find your target object. At this point with a focused image in both scopes, you’ve passed the first obstacle. If you don’t see an image after attempting to focus it in, you might consider aligning your finderscope again. Once you pass this step, you’ll will enjoy the time spent ensuring a good alignment. Every object you center in the finderscope will be easily found in the main telescope tube, which is important for continuing your exploration of the night sky.

3.The low power eyepieces are perfect for viewing the full moon, planets, star clusters, nebulae, and even constellations. These should build your foundation. However, for more detail, try bumping up in magnification to higher power eyepieces on some of these objects. During calm and crisp nights, the light/dark separation line on the moon (called the “Terminator”) is marvelous at high power. You can see mountains, ridges and craters jump out at you due to the highlights. Similarly, you can move up to higher magnifications on the planets and nebulae. Star clusters and stars are best viewed through the low power no matter what.

4.The recurring astronomical theater we call the night sky is an ever-changingbillboard. In other words, not the same movie plays all the time. Rather, the positions of the stars change not only hourly as they seem to rise and set, but also throughout the year. As the earth orbits the sun our perspective on the stars changes on a yearly cycle about that orbit. The reason the sky seems to move daily just as the sun and the moon “move” across our sky, is that the earth is rotating about its axis. As a result you may notice that after a few minutes or a few seconds depending on what power you are viewing at, the objects in your telescope will move. At higher magnifications especially, you will notice that the moon or Jupiter will “race” right out of the field of view. To compensate, just move the fine adjustment controls on your telescope to “track” it in the necessary path.

Helpful Hints

1.Your telescope is a very sensitive instrument. For best results and fewer vibrations set your telescope up on a level location on the ground rather than your concrete driveway or your wooden deck. This will provide a more stable foundation for viewing, especially if you’ve drawn a crowd with your new telescope.

2.If possible view from a location that has relatively few lights. This will allow you to see much fainter objects. You’d be surprised how much more you’ll see from your local lake or park when compared to a backyard in the city.

3.Using your telescope out a window is NEVER recommended.

4.View objects that are high in the sky if possible. Waiting until the object rises well above the horizon will provide a brighter and crisper image. Objects on the horizon are viewed through several layers of earth’s atmosphere. Ever wonder why the moon appears orange as it sets on the horizon. It’s because you are looking through a considerable more amount of atmosphere than you would directly overhead. (Note: If objects high in the sky are distorted or wavy, you are probably viewing on a very humid night.) During nights of unstable atmosphere, viewing through a telescope can be frustrating if not impossible. Astronomers refer to crisp, clear nights as nights of “good seeing.”


Where do I start?

Your telescope can bring the wonders of the universe to your eye. While this manual is intended to assist you in the set-upand basic use of this instrument, it does not cover everything you might like to know about astronomy. The first thing you need to do is get a very simple star chart and a flashlight with a red bulb or red cellophane over the end. For objects other than stars and constellations, a basic guide to astronomy is a must. Some recommended sources appear on our website at www.bushnell.com. Also on our website will be current events in the sky for suggested viewing. But, some of the standbys that you can see are:

The Moon--awonderful view of our lunar neighbor can be enjoyed with any magnification. Try viewing at different phases of the moon. Lunar highlands, lunar maria (lowlands called “seas” for their dark coloration), craters, ridges and mountains will astound you.

Saturn--evenat the lowest power you should be able to see Saturn’s rings and moons. This is one of the most satisfying objects in the sky to see simply because it looks like it does in pictures. Imagine seeing what you’ve seen in textbooks or NASA images from your backyard!

Jupiter--thelargest planet in our solar system is spectacular. Most noted features are its dark stripes or bands both above and below its equator. These are the north and south equatorial belts. Also interesting are Jupiter’s four major moons. Pay close attention to their positions from night to night. They appear to be lined up on either side of Jupiter.

Mars--TheGreat Red Planet appears as areddish-orangedisk. Look at different times of the year and try to catch a glimpse of the white polar ice caps.

Venus--justlike the moon, Venus changed phases from month to month. Some views of brilliant Venus appear as if you were looking at a distant crescent moon.

Nebulae--TheGreat Orion Nebula is a very well known night sky object. This and many others are brought to you by this telescope.

Star Clusters--Viewmillions of stars densely packed in a cluster that resembles a ball.

Galaxies--Oneof the greatest and most interesting galaxies is our neighbor the Andromeda Galaxy. Enjoy this and many others.

Much, much, more!

The image I see in the telescope appears tilted

This is natural and due to the position of the eye

when using the 30x Erect Image Eyepiece

in relation to the telescope tube. The real benefit of the



eyepiece is to deliver an image that is able to be used



when viewing on land.


How do I determine the power my telescope ?

The power of your telescope can be determined



by dividing the focal length of the objective lens by the



focal length of the eyepiece. The eyepiece focal length



is the number printed on the eyepiece. (For example:



700 / 25 = 28X)


Where do I find the Telescope Focal Length

The telescope focal length is the same focal



length as the objective focal length. For this telescope it



is 700mm. Telescope focal lengths range from 600mm



to 900mm on most telescopes.


What can I see with my telescope ?

Telescopes with power ranging from 25X to



50X can be used to view Star Clusters and Nebulae.



90X to 120X telescope can view galaxies. Most planets



can be seen at 150X and higher.


What do the numbers on the eyepiece mean ?

The numbers on the eyepiece represents the



“focal Length” of the eyepiece.


If after you have set-upyour new telescope you are unable to see any objects, use this Quick Reference guide to help you to understand the cause of the problem and quickly determine a remedy


I’ve completed the set-upyet I cannot see anything

Check to see if objective lens cover has



been removed.



Try to view an object that is 200 or more



yards away.



If there is more than one eyepiece included



with the telescope, use the lowest power (highest



number) eyepiece to begin viewing.



Use the Rack & Pinion Focusing Mecha-



nism (3) to bring the object you are trying to view



into focus
