Levenhuk Strike PRO Telescopes

Congratulations on your purchase of a high-quality Levenhuk telescope! These instructions will help you set up, properly use, and care for your telescope. Please read them thoroughly before getting started.

CAUTION! Never look directly at the Sun – even for an instant – through your telescope or nderscope without a professionally made solar lter that completely covers the front of the instrument, or permanent eye damage may result. To avoid damage to the internal parts of your telescope, make sure the front end of the nderscope is covered with aluminum foil or another non-transparent material. Children should use the telescope under adult supervision only.

All parts of the telescope will arrive in one box. Be careful when unpacking it. We recommend keeping the original shipping containers. In the event that the telescope needs to be shipped to another location, having the proper shipping containers will help ensure that your telescope survives the journey intact. Make sure all the parts are present in the packaging. Be sure to check the box carefully, as some parts are small. No tools are needed other than those provided. All screws should be tightened securely to eliminate exing and wobbling, but be careful not to overtighten them, as that may strip the threads. During assembly (and anytime, for that matter), do not touch the surfaces of the optical elements with your ngers. The optical surfaces have delicate coatings on them that can easily be damaged if touched. Never remove lenses or mirrors from their housing, or the product warranty will be null and void.

Telescope assembly

• Slowly loosen the tripod locking knobs and gently pull out the lower section of each tripod leg. Tighten the clamps to hold the legs in place. Spread the tripod legs apart to stand the tripod upright.

• Adjust the height of each tripod leg until the tripod head is properly leveled. Note that the tripod legs may not be the same length when the equatorial mount is leveled.

• Place the accessory tray on top of the bracket, and secure it with thumbscrews from underneath.

• Attach the mount to the tripod head. If the mount does not t on the tripod, loosen the azimuth lock knob. Retighten it after assembly.

• Take the counterweight rod.

• Screw the counterweight rod into the threaded hole on the end of the declination shaft.

• Unscrew the threaded cap from the end of the counterweight rod.

• Take the counterweight(s) and slide them halfway along the counterweight rod. Tighten the counterweight thumbscrews.

• Replace the threaded cap on the end of the counterweight rod.

• Attach the slow-motion controls to the worm gear mechanisms. Tighten the locking screws to secure the control in place.

• Remove the telescope tube from its packaging.

• Remove the ring clamps by releasing their thumbscrews and opening their hinges.

• Using the bolts provided, fasten the ring clamps to the mount with a wrench.

• Place the telescope tube between the rings and balance it. Close the hinges around the telescope and retighten the thumbscrews. Do not overtighten.

Finderscope assembly

• Take the nderscope bracket. Carefully remove the rubber ring.

• Place the ring on the nderscope and position it into the groove halfway along the tube.

• Insert the nderscope bracket into a holder on the telescope tube and lock it in place with a thumbscrew.

• Insert the nderscope into the bracket, so that the rubber ring locks it in place.

Eyepiece assembly

• Unthread the thumbscrews on the focuser tube.

• Insert the diagonal mirror into the focuser tube and secure it by retightening the thumbscrews.

• Unthread the thumbscrews on the diagonal mirror.

• Insert the desired eyepiece into the diagonal mirror and secure it by retightening the

thumbscrews.

Red dot nder

The red dot nder is a zero magnication pointing tool that uses a coated glass window to superimpose the image of a small red dot onto the night sky. The red dot nder is equipped with a variable brightness control, azimuth adjustment knob, and altitude adjustment knob. The nder is powered by a 3-volt lithium battery located underneath at the front.

To use the red dot nder, simply look through the sight tube and move your telescope until the red dot overlaps the object. Make sure to keep both eyes open when sighting. Like all nderscopes, the red dot nder must be properly aligned with the telescope before use. This is a simple process using the azimuth and altitude adjustment knobs.

• Open the battery compartment by pulling down the cover and remove the plastic shipping cover over the battery.

• Turn on the red dot nder by rotating the variable brightness control clockwise until you hear a click. Continue rotating the control knob to increase the brightness level.

• Insert a low power eyepiece into the focuser. Locate a bright object and aim the telescope so that the object is in the center of the eld of view.

• With both eyes open, look through the sight tube at the object. If the red dot overlaps the object, your red dot nder is perfectly aligned. If not, turn its azimuth and altitude adjustment knob until the red dot overlaps the object.

Balancing the telescope

A telescope should be balanced before each observing session. Balancing reduces stress on the telescope mount and allows precise slow-motion movements. A balanced telescope is especially crucial when using the optional clock drive for astrophotography. The telescope should be balanced after all accessories (eyepiece, camera, etc.) have been attached. Before balancing your telescope, make sure that your tripod is balanced and on a stable surface. For photography, point the telescope in the direction you will be taking photos before performing the balancing steps.

R.A. Balancing

• For best results, adjust the altitude of the mount to between 15º and 30º if possible, by using the altitude adjustment T-bolt.

• Slowly unlock the R.A. and Dec. lock knobs. Rotate the telescope until both the optical tube and the counterweight rod are horizontal to the ground, and the telescope tube is to the side of the mount.

• Tighten the Dec. lock knob.

• Move the counterweights along the counterweight rod until the telescope is balanced and remains stationary when released.

• Tighten the counterweight screws to secure the counterweights.

Dec. Balancing

All accessories should be attached to the telescope before balancing around the declination axis. The R.A. balancing should be done before proceeding with Dec. balancing. For best results, adjust the altitude of the mount to between 60º and 75º if possible.

• Release the R.A. lock knob and rotate around the R.A. axis so that the counterweight rod is in a horizontal position. Tighten the R.A. lock knob.

• Unlock the Dec. lock knob and rotate the telescope tube until it is parallel to the ground.

• Slowly release the telescope and determine in which direction it rotates. Loosen the telescope ring clamps and slide the telescope tube forward or backward between the rings until it is balanced.

• Once the telescope no longer rotates from its parallel starting position, retighten the tube rings and the Dec. lock knob. Reset the altitude axis to your local latitude.

Operating the mount

The mount has controls for both conventional altitude (up-down) and azimuth (left-right) directions of motion. These two adjustments are suggested for large direction changes and for terrestrial viewing. To adjust azimuth, loosen the big knob under the mount base and rotate the mount head about the azimuth axis. Use the altitude adjustment T-bolts to set the required altitude. In addition, the EQ2 mount has R.A. (hour angle) and Dec. controls for polar-aligned astronomical observing. Loosen the lock knobs to make large direction changes. Use the slow-motion controls for ne adjustment after the lock knobs have both been locked. An additional scale is included for the altitude axis. This allows polar alignment at your local latitude.

Barlow lens

A Barlow lens increases the magnifying power of an eyepiece, while reducing the eld of view. It expands the cone of the focused light before it reaches the focal point, so that the telescope’s focal length appears longer to the eyepiece. In addition to increasing magnication, the benets of using a Barlow lens include improved eye relief, and reduced spherical aberration of the eyepiece. For this reason, a Barlow plus a lens often outperform a single lens producing the same magnication. And the best advantage is that a Barlow lens can potentially double the number of eyepieces in your collec-

tion.

Focusing

Slowly rotate the focus knobs under the focuser one way or the other until the image in the eyepiece is sharp. The image usually has to be nely refocused over time, due to small variations caused by temperature changes, exures, etc. This often happens with short focal ratio telescopes, particularly when they haven’t yet reached outside temperature. Refocusing is almost always necessary when you change an eyepiece, add or remove a Barlow lens.

Polar adjustment

In order for your telescope to track objects in the sky you have to align your mount. This means tilting the head over so that it points to the North (or South) celestial pole. For people in the Northern Hemisphere this is rather easy as the bright star Polaris is very near the North Celestial Pole. For casual observing, rough polar alignment is adequate. Make sure your equatorial mount is leveled and the nderscope is aligned with the telescope before beginning. Look up your latitude on a map, road maps are good for this purpose. Now look at the side of your mount head, there you will see a scale running from 0 to 90°. Loosen the mount latch slightly rotating the lock handle counterclockwise. A thumbscrew located underneath the mount head pushes the latch plate, thus changing the angle. Turn the screw until the pointer on the latitude scale is set at the latitude of your observation site.

Loosen the Dec. lock knob and rotate the telescope tube until the pointer on the setting circle reads 90°. Retighten the Dec. lock knob. Loosen the azimuth lock knob and move the mount so that the R.A. axis points roughly at Polaris. Use the two azimuth adjustment knobs above the “N” to make ne adjustments in azimuth if needed. For more accurate alignment, look through the nderscope and center the Polaris on the crosshairs using the azimuth and latitude adjustment knobs.

After a while you will notice your target drifting slowly North or South depending on the direction of the pole relative to Polaris. To keep the target in the center of the view, turn only the R.A. slow-motion control. After your telescope is polar aligned, no further adjustments in the azimuth and latitude of the mount should be made in the observing session, nor should you move the tripod. Only movements in R.A. and DEC axis should be made in order to keep an object in the eld. In the Southern Hemisphere you must align the mount to the SCP by locating its position with star patterns, without the convenience of a nearby bright star. The closest star is the faint 5.5-mag. Sigma Octantis which is about one degree away. Two sets of pointers which help to locate the SCP are α and β Crucis (in the Southern Cross) and a pointer running at a right angle to a line connecting α and β Centauri.

Tracking celestial objects

When observing through a telescope, astronomical objects appear to move slowly through the telescope’s eld of view. When the mount is correctly polar aligned, you only need to turn the R.A. slow-motion control to follow or track objects as they move through the eld. If the object is too faint you may want to use setting circles on an equatorial mount. Setting circles al-

low you to locate celestial objects whose celestial coordinates have been determined from star charts. The telescope’s R.A. setting circle is scaled in hours, from 1 to 24, with small lines in between representing 10 minute increments. The upper set of numbers applies to observations in the Northern Hemisphere, while the numbers below them apply to observations in the Southern Hemisphere. Setting (calibrating) the R.A. setting circle: in order to set your Right Ascension circle you must rst nd a star in your eld of view with known coordinates. A good one would be the 0.0 magnitude star Vega in the Constellation Lyra. From a star chart we know the R.A. coordinate of Vega is 18h 36m. Loosen the R.A. and DEC. lock knobs on the mount and adjust the telescope so that Vega is centered in the eld of view of the eyepiece. Tighten the R.A. and DEC. lock knobs to lock the mount in place. Now rotate the R.A. setting circle until it reads 18h36m. You are now ready to use the setting circles to nd objects in the sky.

A German Equatorial mount has an adjustment, sometimes called a wedge, which tilts the mount’s polar axis so that it points at the appropriate Celestial Pole (NCP or SCP). Once the mount has been polar aligned, it needs to be rotated around the polar axis only to keep an object centered. Do not reposition the mount base or change the latitude setting. The mount has already been correctly aligned for your geographical location (i.e. Latitude), and all remaining telescope pointing is done by rotating the telescope tube around the polar (R.A.) and declination axes.

A problem for many beginners is recognizing that a polar-aligned, equatorial mount acts like an alt-azimuth mount which has been aligned to a celestial pole. The wedge tilts the mount to an angle equal to the observer’s Latitude, and therefore it swivels around a plane which is parallel to the celestial (and Earth’s) equator. This is now its “horizon”; but remember that part of the new horizon is usually blocked by Earth. This new “azimuth” motion is called Right Ascension (R.A.). In addition, the mount swivels North (+) and South (-) from the Celestial Equator towards the celestial poles. This plus or minus “altitude” from the celestial equator is called Declination (Dec.). Now, consider pointing the telescope to the western or eastern horizon. If the counterweight is pointing North, the telescope can be swiveled from one horizon to the other around the Dec. axis in an arc that passes through the NCP (any Dec. arc will pass through the NCP if the mount is polar-aligned). It can be seen then that if the optical tube needs to be pointed at an object north or south of this arc, it has to be also rotated around the R.A. axis. Pointing in any direction other than due North requires a combination of R.A. and Dec. positions. Telescopes with long focal lengths often have a “blind spot” when pointing near the zenith, because the eyepiece-end of the optical tube bumps into the mount’s legs. To avoid this, the tube can be very carefully slipped up inside the ring clamps. This can be done safely because the tube is pointing almost vertically, and therefore moving it does not cause a Dec. balance problem. It is very important to move the tube back to the Dec. balanced position before observing other sky areas. Something which can also be a problem is that the optical tube often rotates so that the eyepiece, nderscope and the focusing knobs are in less convenient positions. The diagonal mirror can be rotated to adjust the eyepiece. However, to adjust the positions of the nderscope and focusing knobs, loosen the tube rings holding the telescope tube and gently rotate it. Do this when you are going to observe an area for while, as it is inconvenient to repeat every time you briey go to a new area. Finally, there are a few things to consider to ensure that you are comfortable during the viewing session. First is setting the height of the mount above the ground by adjusting the tripod legs. You must consider the height that you want your eyepiece to be, and if possible plan on sitting on a comfortable chair or stool. Very long optical tubes need to be mounted higher or you will end up crouching or lying on the ground when looking at objects near the zenith. However, a short optical tube can be mounted lower so that there is less movement due to vibration sources, such as wind. This is something that should be decided before going through the effort of polar aligning the mount.

Camera adapter

To attach a camera to your telescope you may need an adapter to get the camera focused. Some reectors require wider motion range than the one allowed by the focuser; some refractors are designed to be used with diagonal mirrors and thus need a longer focal length when used with camera. To achieve that, simply attach an extender to the focuser of your telescope and then attach the camera with a T-adapter to the extender.

Telescope extras and accessories

The unique kit of this telescope sets it apart from the counterparts and makes it a perfect gift for any aspiring astronomer. You will nd everything you need for your observations after unpacking the colorful box, including:

1. “You’ve got a telescope now. What next?” handbook. This practical

handbook was created specically for beginning astronomers. It contains valuable information on over 280 celestial objects and the cosmos in general, as well as colorful star charts and facts on the design of different telescopes.

2. Stellarium. This is a 3D planetarium that allows you to plan your

observations and explore the night sky several years in the future. The database of this software contains over 600,000 stars, planets of the Solar System, the Moon, comets and asteroids, galaxies, nebulae and star clusters. All this can be rendered in just a few moments and studied directly on your computer!

3. Set of posters (The Moon, The Sun and other stars, The Solar

System). These posters will help you explore the universe and learn interesting facts about the Solar system, its planets and satellites, as well as various distant stars. Colorful illustrations and captions present necessary information in an easy-to-read format. The posters are 84 cm x 60 cm (A1).

4. Planisphere. This rotating star chart is a handy tool that allows

you to nd out what celestial objects and constellations are visible above the horizon at a given date and time. All you need to do is align the viewer and the star chart, therefore, providing a date and time.

5. Compass. It is truly an invaluable tool that can help you orient

yourself to the Northern pole on your observation site. Afterwards, it is easy to locate Polaris in the night sky, which provides a starting point for further observations.

We also wanted to make sure that your telescope is protected when moved or stored. Therefore, we have added a telescope case to the kit: Levenhuk Zongo 80 (Strike 900 PRO) or Levenhuk Zongo 60 (Strike 950 PRO, Strike 1000 PRO). The case is made of a sturdy waterproof material and the padded lining protects the telescope from any impacts. The case is also tted with handle straps, full-length zippers and separate compartments for the mount and accessories.

Sooner or later, you will see everything there is to see with the standard kit and decide it is time to delve deeper into the cosmos. The additional accessories we are providing will see to it! We have included:

• a 6.3 mm eyepiece, a wonderful all-purpose eyepiece that allows you to achieve higher magnications, necessary for observations of the Moon and planets;

• a solar lter that allows you to observe the Sun without risking permanent eye damage;

• a lunar lter that reduces the glare of the lunar surface and enhances the details of the landscape;

• four lters that will come in handy for planetary observations, enhancing the features of the surface;

• a 2x Barlow lens that is capable of doubling the focal length of the telescope. It, therefore, dou- bles the magnication of any eyepiece used.

All this allows you to use your Levenhuk Strike PRO to the maximum of its capabilities, opening a gateway into the mysterious cosmos, straight after purchase! These accessories and the telescope itself are safe even for your children to use, and their quality and reliability make sure that you can enjoy high-quality views of the universe for years to come.
