The Celestron Focus Motor provides electronic focusing using a computer or Celestron computerized mount hand controller for remote/hands-free observing. It is specifically designed for use with Celestron Schmidt-Cassegrain (SCT) and EdgeHD telescope optical tubes. With the focus motor installed, you can bring celestial objects into sharp, precise focus using your telescope’s hand controller or a computer instead of using the focuser knob.

Must-Have Accessory for Astroimagers

A focus motor is great for visual observers who want to dial in exact focus (especially those with dexterity issues). With a motorized focuser installed, an astroimager no longer needs to be physically near the telescope to focus an image. Combined with computerized control of the mount and camera, the motor enables you to gather data remotely from a backyard observatory, or even a telescope located hundreds of miles away. As an added bonus, port covers protect the ports while not in use, and the covers cannot be lost due to the tethered design.

Self-Powering

You need not worry about powering the motor. When connected to a Celestron computerized mount, the mount provides the power to the motor. When connected directly to a computer, the motor is powered via USB.

Easy Controls

Motor controls include multiple speed rates, automatic GoTo indexed focuser position, and focuser backlash compensation. In addition, the Focuser Utility software for Windows provides a simple user interface and is also compatible with Celestron PWI. Autofocusing is easy through a camera and third-party software via ASCOM. Indexed focus position allows the motor to automatically return to a previous focus position and prevents the focus motor from reaching the end of telescope’s mechanical focus travel.

Compatible Optical Tubes

The focus motor is compatible with all Celestron SCTs from 6" to 14" in aperture that have been produced since the year 2006. It is also compatible with the 8" Rowe-Ackermann Schmidt Astrograph (RASA), the 36cm RASA, the 7" Maksutov-Cassegrain, and all the EdgeHD optical tubes except for the 9.25". You can also use this focus motor with the 11" RASA tube, but it requires a Focuser Retrofit Kit.
