1. Unpacking
The entire telescope will arrive in three boxes, one containing
the tripod, one containing the equatorial mount, and the third
box containing the optical tube. Be careful unpacking the
boxes. We recommend keeping the boxes and original pack-
aging. In the event that the telescope needs to be shipped to
another location, or returned to Orion for warranty repair, hav-
ing the proper packaging will ensure that your telescope will
survive the journey intact.
Make sure all the parts in the Parts List are present. Be
sure to check each box carefully, as some parts are small.
If anything appears to be missing or broken, immediately
call Orion Customer Support (800-676-1343) or email
[email protected] for assistance.

1. Stand the tripod legs upright and spread the legs out as
far as they will go. Make certain that the leg lock levers are
tightened. Assembly should take no more than 30 min-

telescope requires no tools other than the ones provided.
2. Place the base of the equatorial mount onto the tripod
head. Orient the equatorial mount so that the post on the
tripod head lines up with the azimuth adjustment knobs on

ongratulations on your purchase of a quality Orion telescope. Your new Atlas 10 EQ is designed for
high-resolution viewing of astronomical objects. With its precision optics, and its superb Atlas mount,
you’ll be able to locate and enjoy thousands of fascinating celestial denizens, including planets, Moon,
and a variety of galaxies, nebulas and star clusters. The built in dual internal DC stepper motor drives will
easily track these objects as they move through the night sky.
These instructions will help you set up and properly use your telescope. Please read them over thor-
oughly before getting started.
WARNING:
Never look directly at the Sun
through your telescope or its finder scope—even
for an instant—without a professionally made
solar filter that completely covers the front of the
instrument, or permanent eye damage could
result. Young children should use this telescope
only with adult supervision.
