and the motor drive system will keep the object centered over
time. Remember, never use the slow-motion control knobs
when the manual clutches are engaged or you could perma-
nently damage the motors.
There are four pushbuttons on the hand controller (Figure 9).
If no buttons are pushed, the R.A. motor will turn the R.A. axis
at sidereal rate to track the motion of the night sky. The left
and right buttons move the mount about its R.A. axis and the
up and down buttons move the mount about its Dec. axis. The
rate of speed is determined by the rate switch at the top right
of the hand controller. If the switch is at the 2x position, the
mount will move at two times sidereal rate when the right hand
button is pushed, which will case objects to viewed in the eye-
piece to move slowly eastward. If the left button is pushed, the
drive will stop turning, which will cause objects in the eyepiece to move slowly westward. The top and bottom bottoms will
cause the telescope to move in Declination at the 2x speed.
Similarly, if the switch is at the 4x or 8x position, the mount will
move four times or eight times sidereal rate when a button is
pushed.
The 2x sidereal rate is the best setting for making guiding cor-
rections during long-exposure astrophotography. The 4x and
8x rates are best for centering an object within the telescope’s
eyepiece.
Note that whenever any of the four buttons on the hand con-
troller are pressed, the LED in the center of the controller will
shine red; when the button is released, the LED will be green.
Also, when the LED starts to blink at a constant rate, its time
to change the batteries in the battery pack.
