Focus accurate and fast your Celestron SCT telescope using our powerful Motor Focus Kit Zero. This fast and zero backlash stepper motor has the required torque to focus of your SCT telescope with great precision.

Pulley and Belt design allows the motor to stay away from your filter wheel (and not collide with it) when you use a focal reducer. Its sophisticated SCT bracket design (margarita style) can fit to all new Celestron SCTs (Classic / Edge) and RASA series.

Please note that you will also need a motor controller to drive this motor.

Products that can drive the Motor Focus Kit Zero are:
Dual Motor Focus Controller
Ultimate Powerbox v2 only (v1 is not compatible)
eXternal Motor Controller

Zero backlash stepper motor

Embedded bipolar stepper motor provides a zero backlash drive. Motor is very fast and allows you to quickly move from any focus point to another.

Please note that some older SCT series are not compatible with the SCT bracket so contact us with a photo of your telescope focuser if you are not certain that your telescope can accept the SCT bracket.

SCT Bracket was designed to support Celestron SCT Telescopes. Although, we have seen that it perfectly fits on Meade SCT telescopes that have the round focus knob. Please check the image below if your Meade Telescope is the same as the photo’s. For more information please contact us.

Customer Reviews (4.8 / 5 · 5 reviews)

Evelyn ★★★★★

I was worried about backlash ruining my astrophotography, but this stepper motor eliminated it completely. The torque is impressive for such a compact unit and the focus is now dead-on every time.

Olivia L. ★★★★★

Setup was straightforward and the motor had plenty of torque to move the focuser smoothly even with my heavy eyepiece attached. Focus snaps in instantly now, no more hunting back and forth.

Violet ★★★★★

The zero backlash on this stepper motor is no joke; it locks onto focus without that annoying drift I used to get. I can finally dial in a crisp image on my SCT in seconds rather than fumbling. It's a game changer for planetary imaging.
