Celestron Focus Motor for SCT and EdgeHD
Focusing doesn't have to be a pain thanks to the Celestron Focus Motor! This innovative Celestron Focus Motor can be used with an SCT or EdgeHD scope to focus your system electronically using a computer or Celestron computerized mount hand controller. This allows for an essentially hands-free approach when bringing celestial objects into a crisp focus.
Astrophotographers will love this focusing device! Astrophotographer can achieve crisp sharp photos with exact focus thanks to the electronic focusing system. If the focus motor itself was not enough, port covers protect the ports when not in use, and the covers cannot be lost due because of the tethered design.
There are a few different ways you can connect the Focus Motor to your telescope. 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 mount’s hand controller (NexStar+ or StarSense) or a computer. When connected to a computer, the USB will provide the power, similar to the mount. You can also use an external 12V DC power source (not included) which plugs into the motor’s power jack
The controls for the motor include the following: multiple speed rates, an automatic GoTo indexed focuser position, and a focuser backlash compensation. The Indexed focus position allows the motor to move to a previous position and prevents the motor from reaching the telescope's mechanical focus travel.
The Focuser Utility software, made for Windows, has a simple user interface and is compatible with Celestron PWI. It also enables autofocusing with a camera and third-party software via ASCOM
Celestron offers a free software called Focuser Utility for computer control. The Celestron PWI software also suffices. To use a third-party focuser control software, an ASCOM driver is required.
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.
