1. Unpacking

The entire telescope will arrive in one box. Be careful unpack-
ing 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 mount 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.

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 telescope’s front meniscus lens or the
lenses of the finder scope or eyepieces with your fingers. The
optical surfaces have delicate coatings on them that can eas-
ily be damaged if touched inappropriately. Never remove any
lens assembly from its housing for any reason, or the product
warranty and return policy will be voided.

1. Stand the tripod legs upright and spread the legs out as far

as they will go. Keep the tripod legs at their shortest (fully
retracted) length, for now; you can extend them to a more
desirable length later, after the scope is fully assembled.

C

ongratulations on your purchase of an Orion telescope. Your new SkyView Pro 127mm EQ is designed

for, high-resolution viewing, and astrophotography of astronomical objects. With its precision optics and
sturdy 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.
