2 . Align : Instructs the telescope to use a selected star or
object as an alignment position .
3 . Direction Keys : Allows complete control of the telescope
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 hand control has keys on the hand
control to allow direct access to each of the catalogs in its
database . The hand control 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 telescope’s 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 .
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 telescope 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
telescope’s 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 all Celestron computerized 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 .

In order for the telescope to accurately point to objects in the
sky, it must first be aligned with known positions (stars) in the sky .
With this information, the telescope can create a model of the
sky, which it uses to locate any object with known coordinates .
There are many ways to align your telescope with the sky
depending on what information the user is able to provide:
