Figure 22. Losmandy dovetail saddle
After switch the Stationary and Locking Blocks, make sure that the alignment mark on the Stationary
Block is aligned to one of the position marks on the saddle plate. If you have a wider dovetail plate,
move the Stationary Block to an outside mark. For a narrow plate, move the Stationary Block to an
inside mark. The marks are located on both end of the saddle plate.
STEP 8. Balance the Payload
Before mounting an OTA, make sure the arrow on dovetail saddle is facing front. If it is not,
release DEC gear switch and rotate dovetail saddle 180°.
After attaching the scope and accessories, the mount head assembly must be balanced in both DEC
and RA axes to ensure minimum stresses on the mount driving mechanism.
CAUTION: The telescope may swing freely when the R.A. or DEC Gear Switch is
disengaged. Always hold on to the mount and/or telescope assembly before releasing
the Gear Switches to prevent it from swinging, which can cause personal injuries and/or
equipment damages.
Set the mount at Zero Position. Disengage both RA and DEC gear switches and move the mount to
horizontal position to check balance. Return to Zero Position for balance adjustment. Balance the DEC
axis by moving the scope with accessories back and forth in the mount saddle or within the scope
mounting rings. Balance the assembly in R.A. axis by moving CW along its shaft. Repeat the process
until both DEC and RA axes are balanced.
CAUTION: The balancing process MUST be done with Gear Switch at the total disengaged
position! Otherwise it might damage the worm system.
