This dual axis motor drive, with drive corrector capabilities, is designed for Celestron's CG-5 and GP mounts. Three speeds are available - (1x) sidereal, 1.3x for guiding and 6x for centering.
The motor drive operates on a 9 volt battery that goes into the handheld controller, not the separate battery pack that comes with the lower quality Celestron motor drives. Motors for both axes are included, along with brackets, clutches and hardware. The part number is Celestron 93820-C.
The gears are teflon which makes for a quieter setup. One of the tiny set screws that holds the gear onto one of the hubs stripped, and the gear was glued to the hub which fits over the motor drive shaft. It was set in the exact same place as with the set screw location, i.e., it butts up against the black hub, thus not affecting performance. It is in excellent condition.
The drives, etc., sell for $399.95 + shipping, if you can find them. The cost of this unit, which I only used a few times on my CG-5 (sold the CG5 to get a G11), is $275 including shipping in CONUS. Money order or Paypal preferred (add 3% for Paypal).
Thanks for looking.
