The Orion ShortTube 80 can be outfitted for nighttime star-
gazing, daytime terrestrial observation, as a guidescope for
astroimaging, or as a telephoto lens attached to an SLR/
DSLR camera body.

Attaching a Finder Scope

An Orion finder scope can be attached to the ShortTube 80
to provide a low power, wide field view helpful in aiming the
telescope. Your finder scope bracket can be mounted in the
dovetail shoe molded into the focuser assembly. Loosen the
finder scope lock knob and slide the dovetail foot of your
finder bracket in place. Secure it by re-tightening the lock
knob.
