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 Advanced GT 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 Advanced GT 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 Advanced GT database.

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

7.Enter: Pressing Enter allows you to select any of the Advanced GT 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 rates 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 telescope remotely.

Hand Control Operation

This section describes the basic hand control procedures needed to operate the GT Series Telescopes. 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 calibrating your mount, polar alignment and backlash compensation.
