STEP 6. Balance the Payload
After attaching the scope and accessories, the mount head assembly must be balanced in both R.A.
and DEC 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.
Return the mount to Zero Position after balancing and engage gear switches.
STEP 7. Connect Cables
Plug in a 12V DC power supply to the DC12V power socket (size 5.5mm/2.5mm). Connect the
®
Go2Nova 8407+ Hand Controller to the HBX port on the mount base panel.
