I have a set of dual axis drives for CG-5 / EQ-4 mounts. My understanding is that they also fit the Orion Skyview Pro mounts as well as the Vixen Great Polaris and similar CG5 and EQ4 mounts.
They are the newer style with the precision brass gears, and track very accurately. They are in extremely good condition, and have only been used a handful of times. I used them this past spring to observe Jupiter at 500x with no noticable errors in tracking, or vibration whatsoever.
Includes all standard hardware, clutches, hand controller, and leatherette battery pack.
Selling because I upgraded my mount to a custom GOTO system.
