Congratulations on your purchase of a quality Orion telescope. Your new SkyView Pro 100mm ED EQ
is an exceptional instrument for observing and imaging astronomical objects. The ED glass of the objec-
tive lens ensures you'll enjoy star, Moon, and planetary images with far less color distortion than seen
in standard refractors. Other features, such as the smooth Crayford focuser, precision machined lens
cell, and deluxe aluminum focusing knobs also attest to the overall high quality of the telescope. With the
sturdy SkyView Pro equatorial mount, you'll be able to enjoy steady viewing of thousands of the night
sky's fascinating celestial targets.
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.

1. unpacking

The SkyView Pro 100mm ED EQ will arrive in one box; be care-
ful 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 anything appears to be missing or broken, immediate-
ly call Orion Customer Support (800-676-1343) or email
support@telescope.com for assistance.

3. assembly

Assembling the telescope for the first time should take about
30 minutes. No tools are needed other than the provided cres-
cent wrench. 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 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.
