1. unpacking

The entire telescope system will arrive in one box. Be careful 
unpacking the box. We recommend keeping the original ship-
ping containers. In the event that the telescope needs to be 
shipped to another location, or returned to Orion for warranty 
repair, having the proper shipping containers 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 boxes 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.  No  tools  are  needed  other  than  the  ones  pro-
vided.  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 scopes or eyepieces with your fingers. The optical sur-

C

ongratulations on your purchase of a quality Orion telescope. Your new SpaceProbe 130mm EQ is 

designed  for  high-resolution  viewing  of  astronomical  objects. With  its  precision  optics  and  equatorial 
mount, you’ll be able to locate and enjoy hundreds of fascinating celestial denizens, including the plan-
ets, Moon, and a variety of deep-sky galaxies, nebulas, and star clusters.
If you have never owned a telescope before, we would like to welcome you to amateur astronomy. Take 
some time to familiarize yourself with the night sky. Learn to recognize the patterns of stars in the major 
constellations. With a little practice, a little patience, and a reasonably dark sky away from city lights, 
you’ll find your telescope to be a never-ending source of wonder, exploration, and relaxation.
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. Be sure to also 
cover the front of the finder scope with aluminum 
foil or another opaque material to prevent physical 
damage to the internal components of the scope itself 
as well as to your eye. Young children should use this 
telescope only with adult supervision.
