Adjusting the Mount in Altitude

Adjusting the Mount in Azimuth

For the purpose of polar alignment, there are two directions in which the mount can be adjusted; vertically, which is called altitude and horizontally, which is called azimuth. There are several ways to align on the celestial pole, many of which are discussed later in this manual. This section simply covers the correct movement of the mount during the polar alignment process. To adjust the mount in altitude (i.e., raise or lower the angle of the polar axis), turn the altitude adjustment screw:

Turning the knob clockwise increases the angle at which the polar axis is pointing

Turning the handle counterclockwise lowers the angle at which the polar axis is pointing.

The latitude adjustment on the CG-4 and CG-5 mount has a range of 40°, starting at 20° going up to 60°.

For rough adjustments in azimuth, simply pick up the telescope and tripod and move it. For fine adjustments in azimuth:

1.Turn the azimuth adjustment screws located on either side of the azimuth housing at the base of the mount. While standing behind the telescope, the knobs are on the front of the mount.

Turning the right adjustment knob clockwise moves the mount toward the right.

Turning the left adjustment knob clockwise moves the mount to the left.

Both screws push off of the peg on the tripod head, which means you may have to loosen one screw while tightening the other. The screw that holds the equatorial mount to the tripod may have to be loosened slightly.
