Celestron CPC Deluxe 925 HD Computerized Telescope CPC Deluxe HD Manual - Page 10

HAND CONTROL The CPC is controlled by Celestron's NexStar hand controller designed to give you instant access to all the functions the CPC 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 CPC's 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 CPC to use a selected star or object as an alignment position. 3. Direction Keys: Allows complete control of the CPC 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 hand control has keys to allow direct access to each of the catalogs in its database. The hand control contains the following catalogs in its database: 1 List - For quick access, all of the best and most popular objects in the NexStar database have been broken down into lists based on their type and/or common name: Named Stars Named Objects Double Stars Variable Stars Asterisms CCD Objects IC Objects Abell Objects Common name listing of the brightest stars in the sky. Alphabetical listing of over 50 of the most popular deep sky objects. Numeric-alphabetical listing of the most visually stunning double, triple and quadruple stars in the sky. Select list of the brightest variable stars with the shortest period of changing magnitude. A unique list of some of the most recognizable star patterns in the sky. A custom list of many interesting galaxy pairs, trios and clusters that are well suited for CCD imaging with the CPC telescope. A complete list of all the Index Catalog deep-sky objects. A complete list of all the Abell Catalog deep-sky objects. 7 2 8 3 9 4 10 5 11 6 12 FIGURE 4-1 The NexStar Hand Control 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 and the Sun. Stars - A compiled list of the brightest stars from the SAO catalog. 8 5. Info: Displays coordinates and useful information about objects selected from the NexStar database. 6. Tour: Activates the tour mode, which seeks out all the best objects for the current date and time, and automatically slews the CPC to those objects. 7. Enter: Pressing Enter allows you to select any of the CPC 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 CPC remotely. >> Hand Control Operation This section describes the basic hand control procedures needed to operate the CPC. 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, tracking rate and setting filter and slew limits; finally, the last section reviews all of the utilities functions such as PEC, polar alignment and hibernating the telescope. >> Alignment Procedures In order for the CPC to accurately point to objects in the sky, it must first be aligned to known positions (stars) in the sky.
