1. unpacking
The entire telescope system will arrive in one box. Be careful
unpacking the box. We recommend keeping all of the 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 packaging will help ensure that your tele-
scope will survive the journey intact.
Make sure all the parts in the Parts List are present. Be sure
to check the box carefully, as some parts are small. If anything
appears to be missing or broken, immediately call Orion
Customer Support (800-676-1343) for assistance.

3. assembly
Assembling the telescope for the first time should take about
30 minutes. You will need a Phillips head screwdriver and a
flat head screwdriver. All screws should be tightened securely
to eliminate flexing and wobbling, 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 mirrors or the lenses of
the finder scope or eyepieces with your fingers. The optical
surfaces have delicate coatings on them that can easily be
damaged if touched inappropriately. NEVER remove any lens
assembly from its housing for any reason, or the product war-
ranty and return policy will be voided.
1. Lay the altazimuth mount on its side. Attach the tripod
legs, one at a time, to the base of the mount by sliding a
tripod attachment screw through the top of a leg and

elcome to the exciting world of amateur astronomy! Your SpaceProbe 3 Altazimuth Reflector is a high-
quality optical instrument designed for nighttime stargazing. With its precision optics and intuitive altazi-
muth mount, you’ll be able to locate and enjoy fascinating denizens of the night sky, including the planets,

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 at the sun with your
telescope or its finderscope—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.
