3. GEM45 Mount Assembly
3.1. GEM45 Mount Assembly
NOTE: The GEM45 mount is a precision astronomical instrument. It is highly recommended that you
read this entire manual and become familiar with the nomenclature and function of all components
before starting assembly.
WARNING: DO NOT rock the counterweight shaft rigorously. This may damage the
worm/drive gear system and such damage will not be covered by warranty.
STEP 1. Remove the mount head from package
The mount head is shipped with the R.A. Gear Switch unlocked to protect the worm/gear system. Turn the
Gear Switch 90° to lock the R.A. gear system before removing it from the box.

STEP 2. Set up tripod
The tripod top is 120 mm in diameter with 2x M6 holes 103 mm apart for mounting. Two additional M6 holes
are for the Alignment Peg (the one on top of a leg is for high latitude use; the other one between two legs is
for low latitudes). Thread the Alignment Peg into the correct M6 hole. Insert the Accessory Tray through
the center rod and secure the setup by tightening Locking Knob from underneath.
