Orion 7880 instruction manual Table of Contents

Congratulations on your purchase of the Orion IntelliScope™ Com- puterized Object Locator. When used with any of the SkyQuest IntelliScope XT Dobsonians, the object locator (controller) will pro- vide quick, easy access to thousands of celestial objects for view- ing with your telescope.

The controller’s user-friendly keypad combined with its database of more than 14,000 celestial objects put the night sky literally at your fingertips. You just select an object to view, press Enter, then move the telescope manually following the guide arrows on the liquid crystal display (LCD) screen. In seconds, the IntelliScope’s high-resolution, 9,216- step digital encoders pinpoint the object, placing it smack-dab in the telescope’s field of view! Easy!

Compared to motor-dependent computerized telescopes systems, IntelliScope is faster, quieter, easier, and more power efficient. And IntelliScope Dobs eschew the complex ini- tialization, data entry, or “drive training” procedures required by most other computerized telescopes. Instead, the IntelliScope setup involves simply pointing the scope to two bright stars and pressing the Enter key. That’s it — then you’re ready for action!

These instructions will help you set up and properly operate your IntelliScope Computer- ized Object Locator. Please read them thoroughly.
