DESCRIPTION

Celestron Focus Motor for SCT and EdgeHD Telescopes

The Celestron Focus Motor for SCT and EdgeHD provides electronic focusing control for Celestron Schmidt-Cassegrain (SCT) and EdgeHD telescope optical tubes. When the focus motor is installed, you can bring objects into sharp, precise focus using your telescope’s hand controller or a computer instead of using the focuser knob. 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 motorized focuser, you no longer needs to be physically near the telescope to focus your exposures. 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.

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 (except the 9.25" EdgeHD), the 8” Rowe-Ackermann Schmidt Astrograph (RASA),  the 36cm RASA, and the 7” Maksutov-Cassegrain.

RASA 11" Users, please note: The 11" RASA requires the Focuser Retrofit Kit for RASA 11 in order to work with the Celestron Focus Motor.

9.25" EdgeHD Users, please note: This focuser is currently not compatible with this optical tube due to mechanical interfaces. A fix is currently in development.

 

Power Options

There are three options for powering your Celestron Focus Motor:

  1. 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.
  2. 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.
  3. You may also opt to use an external 12V DC power source which plugs into the motor’s power jack.

Compatible Software

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.

 

  • The Celestron Focus Motor for SCT and EdgeHD enables electronic focusing using a computer or Celestron computerized mount hand controller for remote/hands-free observing.
  • Motor controls include multiple speed rates, automatic GoTo indexed focuser position, and focuser backlash compensation.
  • Focuser Utility software for Windows provides a simple user interface. Also compatible with Celestron PWI.
  • 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.
