Orion 90 EQ instruction manual Table of Contents, Unpacking, Parts List

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.

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, immediate‑ ly call Orion Customer Support (800-676-1343) or email support@telescope.com for assistance.

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.
