User Guide

All parts of the telescope will arrive in one box. Be careful 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 the ones provided. All screws
should be tightened securely to eliminate flexing and wobbling, but be careful not to overtighten
them, or the threads may strip.
During assembly (and anytime, for that matter), do not touch the surfaces of the telescope
objective lens, the lenses of the finderscope, or eyepiece lenses with your fingers. The optical
surfaces have delicate coatings on them that can easily be damaged if touched inappropriately.
Never remove any lens assembly from its housing, or the product warranty will be null and void.
Congratulations on your purchase of high-quality Levenhuk telescope!
These telescopes are designed for high-resolution viewing of astronomical objects. With their
precision optics, you will be able to locate and enjoy hundreds of fascinating celestial objects,
including the planets, the Moon, and a variety of deep-sky galaxies, nebulas, and star clusters.
If you have never owned a telescope before, we would like to welcome you to amateur
astronomy. Take some time to familiarize yourself with the night sky. Learn to recognize the
patterns of stars in the major constellations. With a little practice, a little patience, and a
reasonably dark sky away from city lights, you'll find your telescope to be a never-ending source
of wonder, exploration, and relaxation.
These instructions will help you set up, properly use, and care for your telescope. Please read
them thoroughly before getting started.
Congratulations!
CAUTION!
Never look directly at the Sun – even for an instant – through your telescope or
finderscope without a professionally made solar filter that completely covers the front of
the instrument, or it may result in permanent eye damage. To avoid damage of the
internal parts of your telescope make sure the front end of the finder scope is covered
with aluminum foil or another non-transparent material. Children should use the
telescope under adult supervision only.

Telescope assembly with the EQ3-2 mount
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 equatorial mount to the tripod head. If the mount does not fit 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.
Telescope and mount assembly

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.
For reflectors:
Take the finderscope.
Insert the finderscope bracket into a holder on the telescope tube and lock it in place with a
thumbscrew.
For refractors:
Take the finderscope bracket. Carefully remove the rubber ring.
Place the ring on the finderscope and position it into the groove halfway along the tube.
Insert the finderscope bracket into a holder on the telescope tube and lock it in place with a
thumbscrew.
Insert the finderscope into the bracket, so that the rubber ring locks it in place.
Finderscope assembly

For refractors and Maksutov telescopes:
Unthread the thumbscrews on the focuser tube.
Insert the diagonal mirror into the focuser tube and secure it by retightening the thumbscrews.
Afterwards, insert the desired eyepiece into the diagonal mirror.
Unthread the thumbscrews on the diagonal mirror.
