Orion® 60mm Multi-Use Guide Scope
with Helical Focuser
#13008
Congratulations on your purchase of the Orion 60mm Multi-Use Guide Scope with Helical Focuser. It’s
a smartly designed, versatile guide scope that can also be used as a straight-through finder scope with
the addition of a 1.25" eyepiece, sold separately. It features a “non-rotating” helical focuser with a builtin, adjustable extension tube that enables the user to quickly achieve sharp focus of guide stars with
your autoguiding camera. The guide scope’s 60mm objective lens gathers 44-percent more light than a
50mm guidescope, putting more potential guide stars on your autoguider’s CCD sensor! Includes dualring mounting bracket with six-point adjustment and Vixen-style dovetail bar.

Attaching the 60mm Multi-Use Guide Scope
The 60mm Multi-Use Guide Scope’s mounting bracket has a Vixenstyle dovetail bar that can be mounted to your telescope in different
ways. First, it fits the Orion dovetail finder scope base included on
many Orion telescopes. Simply slide it into the dovetail base, then
tighten the thumbscrew on the base to secure the guide scope in
place (Figure 2).

dovetail finder scope bases as well as those of some other
manufacturers.
Another method of attachment is to bolt the guide scope bracket to
an optional universal dovetail plate, which you mount on top of your
telescope. The mounting bar has three threaded through-holes: the
center hole has ¼"-20 threads and the two larger holes on either
side of center have M8 x 1.25 threads (Figure 3A). To attach the
guide scope bracket to a universal dovetail plate, one way would
be to insert a ¼"-20 socket head capscrew of proper length up
through the dovetail plate and into the center hole of the bracket’s
dovetail bar, as shown in Figure 3B. Tighten the bolt firmly with an
Allen wrench. Then install the universal plate onto your telescope’s
tube rings or radius blocks (Figure 3C). Alternatively you could
attach the bracket using two M8x1.25 screws in the same manner.
