In addition to the Tour Mode, the CPC telescope has a Constellation Tour that allows the user to take a tour of all the best
objects within a particular constellation. Selecting Constellation from the LIST menu will display all the constellation
names that are above the user defined horizon (filter limits). Once a constellation is selected, you can choose from any of
the database object catalogs to produce a list of all the available objects in that constellation.
To see information and data about the displayed object, press the INFO key.
To slew to the object displayed, press ENTER.
To see the next tour object, press the Up key.

The CPC has four direction buttons (3) in the center of the hand control which control the telescope's motion in altitude (up
and down) and azimuth (left and right). The telescope can be controlled at nine different speed rates.

Pressing the RATE key (11) allows you to instantly change the speed rate of the motors from high speed slew rate to precise
guiding rate or anywhere in between. Each rate corresponds to a number on the hand controller key pad. The number 9 is
the fastest rate (3º per second, depending on power source) and is used for slewing between objects and locating alignment
stars. The number 1 on the hand control is the slowest rate (.5x sidereal) and can be used for accurate centering of objects in
the eyepiece and photographic guiding. To change the speed rate of the motors:
Press the RATE key on the hand control. The LCD will display the current speed rate.
Press the number on the hand control that corresponds to the desired speed. The number will
appear in the upper-right corner of the LCD display to indicate that the rate has been changed.
The hand control has a "double button" feature that allows you to instantly speed up the motors without having to choose a
speed rate. To use this feature, simply press the arrow button that corresponds to the direction that you want to move the
telescope. While holding that button down, press the opposite directional button. This will increase the slew rate to the
maximum slew rate.
When pressing the Up and Down arrow buttons in the slower slew rates (6 and lower) the motors will move the telescope in
the opposite direction than the faster slew rates (7 thru 9). This is done so that an object will move in the appropriate
direction when looking into the eyepiece (i.e. pressing the Up arrow button will move the star up in the field of view of the
eyepiece). However, if any of the slower slew rates (rate 6 and below) are used to center an object in the finderscope, you
may need to press the opposite directional button to make the telescope move in the correct direction.
*Rate 1 and 2 are photographic guide rates and are meant to be used when the telescope is set up on a wedge in equatorial
mode. These rates can be used while set up in altazimuth, however the actual speed rate may differ slightly.

The CPC contains many user defined setup functions designed to give the user control over the telescope's many advanced
features. All of the setup and utility features can be accessed by pressing the MENU key and scrolling through the options:

Tracking Mode

1 = .5x*
2 = 1x (sidereal)*
3 = 4x
4 = 8x
5 = 16x
Nine available slew speeds
This allows you to change the way the telescope tracks depending on the type of mount being
used to support the telescope. The CPC has three different tracking modes:
Alt-Az
This is the default tracking rate and is used when the telescope is placed on
6 = 64x
7 = .5º / sec
8 = 2º / sec
9 = 3º / sec
20
