Orion EQ-G Table of Contents, Unpacking, Assembly, Parts List, Attaching a Telescope, Appendices

Congratulations on your purchase of a quality Orion mount. Your new Atlas EQ-G mount works with many different optical tubes. Designed for astronomical use, the Atlas EQ-G provides a solid, stable foundation for precise navigation of the night sky. The internally housed, dual-axis stepper motors provide smooth slewing and tracking of any celestial object. With a little practice, you’ll find that the Atlas EQ-G mount is an invaluable tool for getting the most out of your astronomical observing sessions.

These instructions will help you set up and properly use your equatorial mount. Please read them over thoroughly before getting started.

1. Unpacking

The entire mount will arrive in three boxes, one containing the tripod, one containing the equatorial mount, and one con- taining the hand controller. Be careful unpacking the boxes. We recommend keeping the boxes and original packaging. In the event that the mount needs to be shipped to another location, or returned to Orion for warranty repair, having the proper packaging will ensure that your mount will survive the journey intact.

Make sure all the parts in the Parts List are present. Be sure to check the 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.

3.Assembly

Refer to Figure 1 as needed during the assembly process.

1.Stand the tripod legs upright and spread the legs out as far as they will go. Make certain that the leg lock levers are tightened. Keep the tripod legs at their shortest (fully retracted) length, for now; you can extend them to a more desirable length later, after the mount is fully assembled.

2.Place the base of the equatorial mount onto the tripod head. Orient the equatorial mount so that the post on the tripod head lines up with the azimuth adjustment knobs on the equatorial mount (Figure 2). You may need to loosen the azimuth adjustment knobs on the equatorial mount in order to fit the mount onto the tripod head.
