The AstroView 120 EQ Refractor Congratulations on your purchase of a quality Orion telescope! Your new AstroView 120 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 planets, 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 constellations; 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. Table of Contents 1.

Assembly Carefully open all of the boxes in the shipping container. Make sure all the parts listed in Section 1 are present. Save the boxes and packaging material.

No tools are needed, other than the ones provided. All bolts should be tightened securely to eliminate flexing and wobbling, but be careful not to over-tighten or the threads may strip. Refer to Figure 1 during the assembly process. During assembly (and anytime, for that matter), DO NOT touch the surfaces of the telescope objective lens or the lenses of the finder scope or eyepieces with your fingers.
