elcome to an exciting new world of adventure! Your SkyQuest XT4.5 Dobsonian is a high-quality opti-
cal instrument designed to bring you dazzling views of the outer reaches of our universe. Easy enough for
kids to use, and portable enough for anyone to carry, the SkyQuest XT4.5 will provide fun and entertain-
ment 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 the night with your new tele-
scope, we recommend that you read through this instruction manual. Not only does it provide accurate
directions for assembly and use, but it also serves as a guide for your first explorations in the sky. It is not
necessary to immediately read the appendix sections at the end of the manual; they contain detailed infor-
mation regarding aligning and cleaning the telescope's optics, which should not be needed initially.
