Orion 120ST EQ, 9005 instruction manual Table of Contents, Parts List

Congratulations on your purchase of a quality Orion telescope! Your new AstroView 120ST EQ Refractor is designed for high-resolution viewing of astronomical objects. With its precision optics and equatorial mount, you’ll be able to locate and enjoy hundreds of fascinating celestial denizens, including the plan- ets, Moon, and a variety of deep-sky galaxies, nebulas, and star clusters.

If you have never owned a telescope, we are pleased 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 con- stellations; a star wheel, or planisphere, available from Orion or from your local telescope shop, will greatly help. 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.
