Congratulations on your purchase of an Orion telescope. Your new Observer II 70mm Altazimuth Refractor
is a terric starter instrument for exploring the exotic wonders of the night sky. Designed to be compact

If you have never owned a telescope before, we would like to welcome you to amateur astronomy. Take

constellations. With a little practice, a little patience, and a reasonably dark sky away from city lights, you’ll
nd 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
