GEM45 mount head

OMR  944.300

Utilizing experiences gained during development of our CEM series, we were able to remove unnecessary bulk giving the GEM45 an incredible 2.8 payload to mount weight ratio. This compact 15.8lb mount can precisely GOTO an object and track with up to 45lbs of gear onboard. With its integrated electronic polar scope (iPolarTM), polar alignment is a snap, even when the pole star is obscured.
