1. Unpacking
The entire telescope system will arrive in one box. Be careful
unpacking the box since some of the contents are small and
easy to overlook. We recommend keeping all the original
packaging. In the event you need to ship the telescope to
another location, or return it to Orion for warranty repair, hav-
ing the proper packaging will help ensure that your telescope
will survive the journey intact.
Make sure all the parts in the parts list are present.
Familiarize yourself with their features and compare them to
the callouts on Figures 1, 2, and 3 when possible. If anything
appears to be missing or broken, immediately call Orion
Customer Support (1-800-676-1343) for assistance.

elcome to the exciting world of amateur astronomy. Your new Observer 70 Altazimuth Refractor is a
quality optical instrument that will deliver countless hours of exciting stargazing, from magnified views of
the Moon, star clusters and nebulas to glimpses of Jupiter’s moons and Saturn’s rings. The Observer 70
