in the “S” position for Southern Hemisphere observers. Make 
sure the motor is engaged, and turn the power switch on the 
hand controller to the “ON” position. The LED in the center 
of the hand controller should be shining green. Tighten the 
mount’s R.A. lock knob. If properly polar-aligned, the mount will 
now be tracking the motion of the night sky, and the telescope 
should hold any astronomical object in its eyepiece steady over 
time. 
To move your telescope to a new object, loosen both the R.A. 
and Dec. lock knobs and move the telescope until it is pointed in 
the general direction of the object you wish to view. Retighten the 
R.A. and Dec. lock knobs. Now, disengage the motor and use the 
R.A. and Dec. slow-motion control cables to center the object in 
the eyepiece’s field-of-view. Re-engage the motor, and the motor 
drive system will keep the object centered over time. Remember, 
never use the R.A. slow-motion control cable when the motor in 
engaged, or you could permanently damage the motor.
There are four buttons on the hand controller. If no buttons 
are pressed, the motor will turn the R.A. axis of the mount at 
sidereal rate. If the bottom right button is pressed, the motor 
will turn at 2x sidereal rate, which will cause objects viewed in 
the telescope’s eyepiece to move slowly eastward. If the bot-
tom left button is pressed, the motor will stop turning (pause), 
which will cause objects in the eyepiece to move slowly 
westward. The bottom two buttons are most useful for guiding 
purposes during long-exposure astrophotography.
Similarly, the top right button on the hand controller moves 
objects in the telescope’s eyepiece quickly eastward, while 
the top left button moves objects quickly westward. 

For the EQ-1M, the top buttons move the mount at 8x sidereal 
rate, while the EQ-2M’s top buttons move the mount at 4x 
sidereal rate. The top two buttons are most useful for centering 
an object within the field of view of an eyepiece.
Note that whenever any of the four buttons on the hand control-
ler are pressed, the LED in the center of the hand controller will 
shine red; when the button is released, the LED will shine green 
again.
