1. unpacking
The entire telescope will arrive in one box. Be careful unpack-
ing the box. We recommend keeping the box and all origi-
nal 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, immediate-
ly call Orion Customer Support (800-676-1343) or email
support@telescope.com for assistance.
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.

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
during 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.
