Precise electronic focusing.
Imagine achieving pinpoint focus on celestial objects with ease. The Celestron Focus Motor lets you do just that. Whether you're a visual observer seeking that perfect focus or an avid astroimager striving for impeccable clarity, this motorised focuser is a game-changer. Say goodbye to the challenges of manually adjusting your focuser knob, especially if you have dexterity issues.
Astroimaging from anywhere.
For astrophotographers, the Celestron Focus Motor is a must-have accessory. With this motor installed, you no longer need to be near your telescope to achieve precise focus. Pair it with computerised control of your mount and camera, and you can gather data remotely from the comfort of your backyard observatory or a telescope located miles away. It's a game-changer for those who want to capture stunning images without being tied to their equipment.
Power Options
Celestron Computerised Mount: Use the supplied AUX cable to power and control the Focus Motor through the mount itself. This allows for easy control from your mount's hand controller (NexStar+ or StarSense) or your computer.
Computer USB Port: If you're not using a Celestron mount, simply connect the Focus Motor to your computer's USB port using a user-supplied USB A-to-B cable.
External 12V DC Power: Alternatively, you can opt for an external 12V DC power source that plugs into the motor's power jack for added flexibility.
Software Integration
To enhance your experience further, Celestron offers a free Focuser Utility program for computer control. Additionally, the Celestron PWI (CPWI) software is fully compatible with the focus motor. If you prefer third-party focuser control software, you'll be pleased to know that an ASCOM driver is also available.
Telescope Compatibility
The Celestron Focus Motor is compatible with a wide range of optical tubes. It works flawlessly with all SCTs from 6" to 14" in aperture produced since 2006, as well as the 8" Rowe-Ackermann Schmidt Astrograph (RASA), the 36cm RASA, the 7" Maksutov-Cassegrain, and all EdgeHD optical tubes. Even the RASA 11 (91075) is compatible with the #94155-A focus motor, with the option of a Focuser Retrofit Kit for RASA 11 for added versatility. This motor is designed to fit seamlessly into your Celestron telescope setup.
