1. Unpacking
The entire telescope system will arrive in one box. Be careful
unpacking the box. We recommend keeping the original ship-
ping container. In the event that the telescope needs to be
shipped to another location, or returned to Orion for warranty
repair, having the proper shipping container will help ensure
that your telescope will survive the journey intact.
Make sure all the parts in the Parts List are present. Be sure
to check box carefully, as some parts are small. If anything
appears to be missing or broken, immediately call Orion
Customer Support (800-676-1343) or email support@tele-
scope.com for assistance.

Welcome to a new world of adventure. Your new StarMax 90mm EQ is designed for high-resolution
observing of astronomical objects, and can also be used for terrestrial exploration. With its precision
optics and equatorial mount, you’ll be able to locate and enjoy hundreds of fascinating celestial objects,
including the planets, Moon, and a variety of deep-sky galaxies, nebulas, and star clusters.
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.

WARNING:
Never look directly at the Sun
through your telescope or its finder scope—
even for an instant—without a professionally
made solar filter that completely covers the
front of the instrument, or permanent eye
damage could result. Young children should use
this telescope only with adult supervision.
