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.
