Tour Mode
The CGE includes a tour feature which automatically allows the user to choose from a list of interesting objects
based on the date and time in which you are observing. The automatic tour will display only those objects that
are within your set filter limits (see Filter Limits in the Setup Procedures section of the manual). To activate
the Tour mode, press the TOUR key (6) on the hand control. The CGE will display the best objects to observe
that are currently in the sky.
•
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.
Constellation Tour
In addition to the Tour Mode, the CGE telescope has a Constellation Tour that allows the user to take a tour of
all the best objects in each of the 88 constellations. 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 the next tour object, press the Up key.
Direction Buttons
The CGE 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.
Rate Button
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 (4º 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
