![]() ![]() If you are not using a Celestron mount, you can power and control the focus motor from a computer USB port.This allows control from the mount’s hand controller (NexStar+ or StarSense) or a computer. When using a Celestron computerized mount, you can power and control the focus motor through the mount using the supplied AUX cable.There are three options for powering your Celestron Focus Motor: The RASA 11 (91075) is compatible with the #94155-A focus motor, but requires the Focuser Retrofit Kit for RASA 11. The RASA 11 V2 (91076) is compatible with the #94155-A without a retrofit kit needed.įor 6” Schmidt-Cassegrain telescopes only, the Off-Axis Guider (#93648) cannot be used when the focus motor is installed due to mechanical interferences. It is not compatible with 5” SCTs or older models. It is compatible with the 8” Rowe-Ackermann Schmidt Astrograph (RASA), the 36cm RASA, the 7” Maksutov-Cassegrain, and all the EdgeHD optical tubes. The focus motor is compatible with all SCTs from 6” to 14” in aperture that have been produced since the year 2006. As an added bonus, port covers protect the ports while not in use, and the covers cannot be lost due to the tethered design. Combined with computerized control of the mount and camera, the focus motor enables the imager to gather data remotely from a backyard observatory, or even a telescope located hundreds of miles away. With a motorized focuser installed, an astroimager no longer needs to be physically near the telescope to focus an image. A focus motor is great for visual observers who want to dial in exact focus (especially those with dexterity issues) and a must-have accessory for astroimagers. 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. The Focus Motor provides electronic focusing for Celestron Schmidt-Cassegrain (SCT), EdgeHD, and RASA telescope optical tubes. 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.Enables autofocusing with a camera and third-party software via ASCOM.Focuser Utility software for Windows provides a simple user interface.Motor controls include multiple speed rates, automatic GoTo indexed focuser position, and focuser backlash compensation. ![]() ![]() Compatible with a wide variety of Celestron Schmidt-Cassegrain, EdgeHD, and Rowe-Ackermann Schmidt Astrograph optical tubes.When connected directly to a computer, USB provides the power. Self-powering: When connected to a Celestron computerized mount, the mount provides the power.The Celestron Focus Motor enables electronic focusing using a computer or Celestron computerized mount hand controller for remote/hands-free observing. ![]()
