This Focus Motor provides electronic focusing for 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. A focus motor is great for visual observers who want to dial in exact focus (especially those with dexterity issues) and is a must-have accessory for astroimagers.

With a motorized focuser installed, an astrophotographer 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: 

• Compatible with all Schmidt-Cassegrain Telescopes from 6” to 14” (in aperture) that have been produced by Celestron since the year 2006. It is NOT compatible with 5” SCTs or older models. If the focus motor is installed on 6" SCTs, the Off-Axis Guider accessory cannot be used due to mechanical inteferences
• Compatible with Celestron's CGX 800 RASA, 36cm RASA, CGX 700 Mak, CGEM II 700 Mak, and all EdgeHD optical tubes
  
• Compatible with Celestron's CGX 1100 RASA or CGX-L 1100 RASA but this requires the Focuser Retrofit Kit for 1100 RASA

Power Options:

There are three options for powering the 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 computer or the mount’s hand controller (NexStar+ or StarSense).
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 USB A-to-B cable (not supplied).
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.
• An ASCOM driver is needed if using third-party focuser control software.

About Celestron
Celestron was founded by Tom Johnson whose first telescope design was a simple 6-inch reflector, built for his young son. He gradually progressed to making larger scopes in more sophisticated designs. Today, the Celestron company is an industry leader in designing and manufacturing optical equipment including telescopes (computerised and non-computerised), binoculars, spotting scopes and its accompanying accessories. Celestron's legacy spans 50 years, and has grown to enjoy recognition from amateurs to serious astronomers globally. The company seeks to remain innovative by growing its product offerings, while supporting science education around the world.
