The NexStar has a removable hand controller built into the side of the fork arm designed to give you instant access to all the
functions the NexStar has to offer. With automatic slewing to over 40,000 objects, and common sense menu descriptions,
even a beginner can master its variety of features in just a few observing sessions. Below is a brief description of the
individual components of the NexStar hand controller:
1. Liquid Crystal Display (LCD) Window: Has a dual-line, 16 character display screen that is backlit for
comfortable viewing of telescope information and scrolling text.
2. Align: Instructs the NexStar to use a selected star or object as an alignment position.
3. Direction Keys: Allows complete control of the NexStar in any direction. Use the direction keys to move the
telescope to the initial alignment stars or for centering objects in the eyepiece.
4. Catalog Keys: The NexStar has keys on the hand control to allow direct access to each of the catalogs in its
database. The NexStar contains the following catalogs in its database:
Messier – Complete list of all Messier objects.
NGC – Complete list of all the deep-sky objects in the Revised New General Catalog.
Caldwell – A combination of the best NGC and IC objects.
