The TDM Adapter from Explore Scientific is specifically designed to attach a Telescope Drive Master (TDM) onto Celestron CGEM and CGEM DX equatorial mounts. The TDM is an electronic control system that dramatically reduces tracking errors that are intrinsic in equatorial drive gears, adding a higher level of accuracy without having to upgrade the entire mount.
