1. Unpacking
The SkyView Pro 120 EQ will arrive in one box. Be careful
unpacking the box. We recommend keeping the box and all
original packaging. In the event that the telescope needs to be
shipped to another location, or returned to Orion for warranty
repair, having the proper box and packaging will help 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 any-
thing appears to be missing or broken, immediately call Orion
Customer Support (800-676-1343) or email support@tele-
scope.com for assistance.

3. Assembly
Assembling the telescope for the first time should take about
30 minutes. No tools are needed other than the ones provid-
ed. All screws should be tightened securely, but be careful not
to over-tighten or the threads may strip. Refer to Figure 1 dur-
ing the assembly process.
During assembly (and anytime, for that matter), do not touch
the surfaces of the lenses of the telescope, finder scope or
eyepieces with your fingers. The optical surfaces have delicate
coatings on them that can easily be damaged if touched inap-
propriately. Never remove any lens assembly from its housing
for any reason, or the product warranty and return policy will
be voided.
C
ongratulations on your purchase of an Orion telescope. Your new SkyView Pro 120 EQ is designed for
high-resolution viewing and astrophotography of astronomical objects. With its precision optics and stur-
dy equatorial mount, you’ll be able to enjoy hundreds of fascinating celestial denizens.
These instructions will help you set up, properly use, and care for your telescope. Please read them over
thoroughly 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.
