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-imag-
ing 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).
Using T-threads
Some Orion telescopes (in this case, used as a guide scope) fea-
ture 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 eye-
piece holder and secure the locking thumbscrew. You can alterna-
tively use a reticle eyepiece if you are not using an autoguider.
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 posi-
tion adjustment knobs clockwise or counter-clockwise to move the
Figure 2. Remove the guide star finder’s nosepiece and thread the
guide star finder body onto your telescope’s T-threads.

axes. Each axis has two position adjustment knobs to provide easy
access at different guide scope orientations.
