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 the box and all
original packaging. In the event you need to ship the telescope
to another location, or return it to Orion for warranty repair,
having the proper packaging will help ensure that your tele-
scope 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 EQ 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

result. Young children should use this telescope
