fully assembled and mounted in the

Mounting the Deluxe Mini
Guide Scope
The DMGS’s mounting bracket has a
dovetail foot that fits the Orion dovetail
finder scope base included on many
Orion telescopes. The guide scope
also comes with a separate dovetail
base, or shoe (Orion part #7214),
with two #8-32 x 3/8" flat Phillips-head
screws and two hex nuts, for custom
installations.
To mount the DMGS on a dovetail plate such as Orion’s Wide or Narrow
Universal mounting plates, or similar plates produced under other brand names,
we’ve included an adapter plate that makes it easy (Figure 1). The DMGS can
then be piggybacked on top of your main instrument’s tube rings, or on a side-
by-side plate, for autoguiding.
On the adapter plate there are three threaded holes. The two outer holes are for
attaching the dovetail base to the adapter plate using the two included #8-32 x
5/8" Phillips head screws (Figure 2a). (These are the longer of the four #8-32
screws.) Once the dovetail base is securely attached, you can mount the adapter
Congratulations on your purchase of the Orion Deluxe Mini 50mm Guide Scope
with Helical Focuser. It’s a wonderfully versatile, compact, and lightweight guide
scope designed for use with the Orion StarShoot AutoGuider, Orion StarShoot
Planetary Imager & AutoGuider, or similar small-chip CCD cameras. It’s ideal
for guiding long-exposure astrophotographs with short to medium focal length
telescopes up to about 1500mm focal length. This deluxe model features a
machined, “non-rotating” helical focuser that enables the user to quickly achieve
sharp focus of guide stars with your autoguiding camera. The guide scope’s
bright, wide-field optics serve up lots of potential guide stars on your autogu-
ider’s CCD sensor, and it’s small enough to stash in an accessory case! What’s
more, this scope can also function as a 50mm illuminated finder scope, with the
addition of the optional #8450 Orion 12.5mm Illuminated Plössl eyepiece!
