1. unpacking
The telescope will arrive in two boxes, one containing the
optical tube assembly and accessories, the other containing
the unassembled Dobsonian base. Be careful unpacking the
boxes. We recommend keeping the original shipping contain-
ers. In the event that the telescope needs to be shipped to
another location, or returned to Orion for warranty repair, hav-
ing the proper shipping containers will help ensure that your
telescope will survive the journey intact.
Make sure all the parts in the Parts List below are present. Be
sure to check boxes carefully, as some parts are small. If any-
thing appears to be missing or broken, immediately call Orion
Customer Support (800-676-1343) for assistance.

elcome to an exciting new world of adventure! Your SkyQuest Dobsonian is a high-quality optical instrument designed to
bring you dazzling views of the outer reaches of our universe. Easy enough for kids to use, and portable enough for any-
one to carry, the SkyQuest will provide fun and entertainment for the entire family. Whether you are brand-new to amateur
astronomy or a seasoned stargazer, get ready for many evenings of enjoyment and fascination. Before venturing into

could result. Young children should use this
telescope only with adult supervision.
