FocusCube Zero for 0 Backlash!

The FocusCube SCT has been replaced by the Focus Cube Zero. Zero allows movement without play and is much faster than the old motor

Focus your Celestron SCT telescope quickly, reliably and accurately using the FocusCube Zero. The evolution of technology in astronomy requires a system that will help focus the telescope with great precision. Fast optics and modern cameras require autofocus every small period of time, as temperature can affect focal length and change the optimal focus position. Pegasus FocusCube Zero was developed to meet all these requirements.

Designed to high quality with modern electronics, FocusCube can provide precise digital focus control from a PC. The device includes a stepper motor for focusing in absolute position. The electronics and stepper motor are enclosed in a compact size box.

The stepper motor provides high speed, focus accuracy and zero backlash. You only need this device to focus! Connect the FocusCube Zero to your SCT telescope.

SCT support

A specially shaped, hard-to-bend black anodized aluminum stand can be attached to most Celestron SCT telescopes. We successfully installed it on:

Version compatible with:

•     Celestron Classic 11
•     Celestron EdgeHD 11
•     Celestron RASA 11

The SCT mount was designed to support Celestron SCT telescopes. Although, we have seen that it fits perfectly with Meade SCT telescopes which have the round focus knob. Please check the picture below if your Meade telescope is the same as the picture. For more information, contact us.

How to pilot this Motofocus?

This Focus motorcycle can only be controlled through 2 solutions:

•     By the Ultimate Power Box
•     By external controller

The advantage over its USB version is that this motor receives its power and control via a single cable, unlike the USB version which must be connected to a 12V power supply in addition to its USB port and probe.

Thus it is the ultimate power box which will provide the power and the orders of movements by the ticket of a computer. Less cable!

This Moto focus can also be used without the powerbox but it will need to be paired with an additional external controller.

✅ We recommend this Motofocus for pure imager systems in addition to the solution with the ultimate powerbox!
