Congratulations on your purchase of an Orion telescope. Your new Observer II 70mm Altazimuth
Refractor is a terrific starter instrument for exploring the exotic wonders of the night sky. Designed to be
compact and easy to use, it will provide many hours of enjoyment for the whole family.
If you have never owned a telescope before, we would like to welcome you to amateur astronomy. Take
some time to familiarize yourself with the night sky. Learn to recognize the patterns of stars in the major
constellations. With a little practice, a little patience, and a reasonably dark sky away from city lights,
you'll find your telescope to be a never-ending source of wonder, exploration, and relaxation.
These instructions will help you set up, properly use, and care for your telescope. Please read them over
thoroughly before getting started.
