The Focus Motor for Celestron SCT and EdgeHD telescopes provides electronic focusing for Celestron Schmidt-Cassegrain (SCT) and EdgeHD optical tubes. With the focus motor installed, you can bring celestial objects into sharp, precise focus using your telescopes hand controller or a computer instead of using the manual focuser knob. A focus motor is great for visual observers who want to dial in exact focus and a must-have accessory for astroimagers where critical focus is essential. With a motor 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 focus motor enables the imager 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.
Compatible Optical Tubes
The focus motor is compatible with all SCTs from 6" to 14" in aperture that have been produced since the year 2006. It is not compatible with 5 "SCTs or older models. It is compatible with all EdgeHD optical tubes, the 8" Rowe-Ackermann Schmidt Astrograph (RASA), the 36cm RASA, and the 7" Maksutov-Cassegrain. It can also be used with the 11 RASA, but requires the Focuser Retrofit Kit for RASA 11.
Powering the electronic focuser
There are three options for powering your Celestron Focus Motor:
When using a Celestron computerized mount, you can power and control the focus motor through the mount using the supplied AUX cable. This allows control from the mounts hand controller (NexStar+ or StarSense) or a computer.
If you are not using a Celestron mount, you can power and control the focus motor from a computer USB port. You will need a user supplied USB A-to-B cable.
You may also opt to use an external 12V DC power source which plugs into the motors power jack. Our power supply (PSU in related products) is compatible with this unit
Celestron offers a free Focuser Utility program for computer control. The Celestron PWI software can also control the focus motor. To use third-party focuser control software, an ASCOM driver is needed.
