FocusCube Zero for SCTs
A must have for successful astrophotography sessions with your SCT telescope
Focus fast, reliable, and accurate your Celestron SCT telescope by using the “FocusCube Zero“.
Designed in high quality with modern electronics, FocusCube can provide digital precise focus control from a PC. The device includes a stepper motor for absolute position focusing. Electronics and stepper motor are enclosed in a compact-sized box.
The Stepper motor provides high speed, focus accuracy, and zero backlash. You only need this device to focus! Attach the FocusCube Zero to your SCT telescope, plug the power, the USB cable, download ASCOM drivers or our Unity platform and you are ready to go!
FocusCube is a standalone device and includes controller functionality.
No physical hand controller is included or required.
DO NOT pair it with the Dual Motor Focus Controller or any other controller in the market.
DO NOT connect this RJ45 port to the Ultimate Powerbox RJ45 Stepper Output
The RJ45 port at the back is only for the hand controller or the included temperature sensor.
Zero backlash stepper motor
The embedded bipolar stepper motor provides a zero-backlash movement. The motor allows you to quickly move from any focus point to another. As there is no reduction gearbox the speed is suitable to move the primary mirror in or out at very fast rates.
Easy and repeatable V-Curve focus
A V-Curve is the result of moving the focus of a telescope from an outside focus position into the focus and then further into the same direction out of focus again.
With FocusCube Zero you can easily achieve nearly perfect v-curve lines leading to a sharply focused image.
A special shaped black anodized aluminium bracket, hard to bend, can be attached to most of the Celestron SCT telescopes.
We have successfully installed it on:
- Celestron Classic & EdgeHD 6, 8, 9.25 (SKU:PEG-FCZERO-SCT68925)
- Celestron Classic & Edge HD 11 (SKU:PEG-FCZERO-SCT11)
- Celestron Classic & Edge HD 14 (SKU:PEG-FCZERO-SCT14)
- Celestron RASA 8” (SKU: PEG-FCZERO-SCT68925)
- Cellestron RASA 11” (V2 – For V1 you will need Celestron Retrofit Kit) (SKU:PEG-FCZERO-SCT11)
- Celestron RASA 14” (SKU:PEG-FCZERO-SCT14)
Please notice that we provide three different SCT versions.
The difference is in the metal pulley bore diameter & the screw length in the package.
Please make sure you have selected the correct type for your telescope.
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 if your Meade Telescope is the same as the photo on the right.
For more information about your Meade compatibility please contact us.
An external digital temperature sensor input is located near the motor connector. A digital probe of one meter (3 feet) length is supplied. The probe can be placed near the focuser so the exact temperature of the focuser / environment can be seen through the supplied software or ASCOM driver (probe is included in package)
Expansion Port / Manual Focus
FocusCube includes an expansion RJ45 port at the back of the enclosure. This port provides input for the temperature sensor. An optional hand controller for manual focus control can be acquired for those who might want to add this functionality
ASCOM and INDI Supported
Firmware upgrade support
Firmware supports re-programming via the USB 2.0 connection using upgrade software ((only available for Windows), for future upgrades which may become available. We constantly receive feedback from our customers and keep updating the firmware and software with new features.
