1. unpacking
The entire telescope will arrive in three boxes, one contain‑
ing 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, immediate‑
ly call Orion Customer Support (800‑676‑1343) or email
[email protected] for assistance.

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.
