Celestron CGE1100 Named Stars, Named Objects, Double Stars, Variable Stars, Asterisms, IC Objects

4.Catalog Keys: The CGE has keys on the hand control to allow direct access to each of the catalogs in its database. The CGE 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.

Planets - All 8 planets in our Solar System plus the Moon.

Stars – A compiled list of the brightest stars from the SAO catalog.

List – For quick access, all of the best and most popular objects in the CGE database have been broken down into lists based on their type and/or common name:

Named Stars	Common name listing of		the brightest stars in the
	sky.
Named Objects	Alphabetical listing of over 50 of the most popular
	deep sky objects.
Double Stars	Numeric-alphabetical listing of the most visually
	stunning double,	triple and quadruple stars in the
	sky.
Variable Stars	Select list of the brightest variable stars with the
	shortest period of changing magnitude.
Asterisms	A unique list of some of the most recognizable star
	patterns in the sky.
CCD Objects	A custom list of many interesting galaxy pairs, trios
	and clusters that are well suited for CCD imaging
	with the CGE telescope.
IC Objects	A complete list of all the Index Catalog deep-sky
	objects.
Abell Objects	A custom list of	the	Abell Catalog deep-sky
	galaxies.
Constellation	A complete list of all 88 constellations.

5.Info: Displays coordinates and useful information about objects selected from the CGE database.

6.Tour: Activates the tour mode, which seeks out all the best objects for the current date and time, and automatically slews the CGE to those objects.

7.Enter: Pressing Enter allows you to select any of the CGE functions and accept entered parameters.

8.Undo: Undo will take you out of the current menu and display the previous level of the menu path. Press Undo repeatedly to get back to a main menu or use it to erase data entered by mistake.

9.Menu: Displays the many setup and utilities functions such as tracking rate and user defined objects and many others.

10.Scroll Keys: Used to scroll up and down within any of the menu lists. A double-arrow will appear on the right side of the LCD when there are sub-menus below the displayed menu. Using these keys will scroll through those sub-menus.

11.Rate: Instantly changes the rate of speed of the motors when the direction buttons are pressed.

12.RS-232 Jack: Allows you to interface with a computer and control the CGE remotely.

Hand Control Operation

This section describes the basic hand control procedures needed to operate the CGE. These procedures are grouped into three categories: Alignment, Setup and Utilities. The alignment section deals with the initial telescope alignment as well as finding objects in the sky; the setup section discusses changing parameters such as tracking mode and tracking rate; finally, the last section reviews all of the utilities functions such as the calibrating your mount, PEC and backlash compensation.
