Orion® X-Y Guide Star Finder
#52061
Congratulations on your purchase of the Orion X-Y Guide Star 
Finder. Your Guide Star Finder enables you to easily acquire a 
guide star through your guide scope without the need to physically 
move the position of the guide scope. This convenient astro-imaging accessory thereby eliminates the need to use adjustable guide 
scope tube rings which also reduces tracking problems associated 
with tube flexure.
Attaching the X-Y Guide Star 
Finder to a Guidescope
The Guide Star Finder is equipped with a standard removable 
1.25" nosepiece and female camera T-threads, ready to attach to 
most telescopes. You can either insert the Guide Star Finder like 
an eyepiece using the 1.25" nosepiece, or attach it directly to your 
guide scope focuser using the T-threads.
Using the 1.25" Nosepiece
If your telescope features a 1.25" focuser or adapter, the easiest 
way to attach the Guide Star Finder is by using the included 1.25" 
nosepiece. Simply insert the nosepiece into your telescope’s 1.25" 
adapter and secure it by tightening the thumbscrew (Figure 1).

T-threads
Using T-threads
Some Orion telescopes (in this case, used as a guide scope) feature focus adapters with exterior T-threads. If you are using such 
a telescope, you can attach the Guide Star Finder body directly 
to the T-threads without using the 1.25" nosepiece. Remove the 
1.25" nosepiece. Then carefully attach the Guide Star Finder body 
to the T-threads (Figure 2).
Attaching an Autoguider to the X-Y Guide Star Finder
The X-Y Guide Star Finder’s 1.25" eyepiece holder accommodates 
any standard autoguider with a 1.25" nosepiece (such as the Orion 
StarShoot AutoGuider). Simply insert the autoguider into the eyepiece holder and secure the locking thumbscrew. You can alternatively use a reticle eyepiece if you are not using an auto guider.
The Guide Star Finder requires approximately 38mm of additional 
inward focus travel. 
Adjusting the X-Y Guide Star 
Finder
The Guide Star Finder moves your autoguider within the focal 
plane of your guide scope to find a guide star. If, for example, a 
guide star is not found in the center of the guide scope’s focal 
plane, a star may still exist somewhere off-axis in the same focal 
plane. By adjusting the position of the Guide Star Finder, you can 
find and center a guide star anywhere in the focal plane without 
physically moving the guide scope.
The Guide Star Finder can be adjusted in the “X” and “Y” axes, 
or relative up/down and left/right (Figure 3). Simply turn the position adjustment knobs clockwise or counter-clockwise to move the

Care and Storage
The X-Y Guide Star Finder is very durable, but it should be treated
