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:
The NexStar Hand Control
FIGURE 4-1
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.
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 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 CPC telescope .
IC Objects A complete list of all the Index Catalog
deep-sky objects.
Abell Objects A complete list of all the Abell Catalog
deep-sky objects.
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 . With this information,
