Focus accurate and fast your Celestron SCT telescope using our powerful motor focus kit SCT. This high resolution geared box has a 0,06 degree step size can can easily lift more than 6 Kg (per cm). Its high torque is suitable for lifting heavy imaging equipment. Moreover motor’s gearbox has a low backlash which can easily tuned using backlash compensation in imaging software. An RJ45 socket pinout can be easily converted to a compatible pinout with Moonlite and Robofocus controllers.

Pulley and Belt design allows the motor to stay away from your filter wheel (and not collide with it) when you use a focal reducer. Its sophisticated bracket design can fit to all Celestron SCTs
