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, some 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 lever:
• Turning the lever clockwise increases the angle at which the polar axis is
pointing
• Turning the lever counterclockwise lowers the angle at which the polar axis is
pointing.
The latitude adjustment on the 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. 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.
