Figure 1. The ShortTube 80 Optical Tube Assembly

Congratulations on your purchase of the Orion ShortTube 80 Optical Tube Assembly! This fine-quality versatile instrument can be used for a wide variety of applications. Compact, portable, and easy to use, this telescope will provide many hours of enjoyment for novice and experienced astronomers alike.

The Short Tube 80 Optical Tube Assembly (OTA) arrives from the factory fully assembled and collimated. No adjust- ments should need to be made to the optics. Please keep the original shipping box in the unlikely event you should need to ship the telescope back to Orion for warranty repair service. The box also makes a very good container for stor- ing the telescope when it is not in use.

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.
