I fitted this ra drive motor to the slow motion control. I had to drill out the hole in the coupling a bit to fit the shaft. (I have since found out that you can buy different sized flexable couplings on ebay) It runs of a 9v battery which lasts for weeks. It was celestron branded from aust geo shop for $50 but I think that they have been discontinued but are still available on ebay.
