Adjusting the Mount in Altitude
• To increase the latitude of the polar axis, tighten the rear latitude adjustment screw and loosen the front screw (if
necessary).
• To decrease the latitude of the polar axis, tighten the front (under the counterweight bar) latitude adjustment screw
and loosen the rear screw (if necessary).
The latitude adjustment on the CG-5 mount has a range from approximately 30° going up to 60°.
It is best to always make final adjustments in altitude by
moving the mount against gravity (i.e. using the rear
latitude adjustment screw to raise the mount). To do this
you should loosen both latitude adjustment screws and
manually push the front of the mount down as far as it
will go. Then tighten the rear adjustment screw to raise
the mount to the desired latitude.
For Advanced GT users, it may be helpful to remove the
front latitude adjustment screw completely. This will
allow the mount to reach lower latitudes without the
screw coming into contact with the R.A. motor assembly.
To remove the latitude screw, first use the rear screw to raise the mount head all the way up. Then remove the front
latitude screw completely. Now you should be able to manually move the mount head all the way to its lowest
latitude. Now, using only the rear screw, raise the mount to your desired latitude.
Adjusting the Mount in Azimuth
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 knobs located on either side of the azimuth housing (see Fig 2-14). 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.
Keep in mind that adjusting the mount is done during the polar alignment process only. Once polar aligned, the
mount must NOT be moved. Pointing the telescope is done by moving the mount in right ascension and declination,
as described earlier in this manual.

The Advanced Series mount comes with a declination cable that connects from the R.A. motor drive electronic panel
to the Dec motor drive. To attach the motor cable:
