My astronomy club was given a 8" schmidt cass from a member who passed away. All I know about it is: It's a 8" schmidt cass, RA drive, and it says Quartz on the side. Blue tube, black base. The little motor is a 1/8 rpm AC synchronous motor. It's siezed or burned up, either way it won't run. And that's the part we need.
If you have one, or know where I can get one please email me.
