(polar axis). Consult the manual that came with your equato-

rial mount for details on how to polar-align it.

For observers in the Northern Hemisphere, the N/S switch on

the hand controller should be in the “N” position, and should be

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.
