Pegasus FocusCube V3 Motor Focus (For Celestron SCT Telescopes)

A must have for successful automated astrophotography sessions, this Auto-Focuser is fast, reliable and designed with high quality materials and modern electronics. FocusCube can provide digital precise focus control from a PC.

The device includes a stepper motor for very accurate position focusing with all the electronics and stepper motors enclosed in a compact-sized box.

The stepper motor provides high speed, focus accuracy, and zero backlash. Attach the FocusCube Zero to your Celestron SCT telescope with the correct adapter, plug in the power, the USB cable and download ASCOM drivers or the Pegasus Unity platform and you are ready to go!

IMPORTANT NOTES:
FocusCube is a standalone device and includes full focus control functionality. No physical hand controller is included or required.
DO NOT pair it with the Dual Motor Focus Controller or any other controller on 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 or focuser 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 achieve a nearly perfect v-curve leading to a sharply focused image.

SCT bracket:
A special shaped black anodised aluminium bracket, which is stiff and hard to bend, can be attached to most of the Celestron SCT telescopes. Pegasus has successfully tested them on the following:

• Celestron Classic & EdgeHD 6, 8, 9.25
  
• Celestron Classic & Edge HD 11
  
• Celestron Classic & Edge HD 14
  
• Celestron RASA 8"
  
• Celestron RASA 11" (V2 - for V1 you will need a separate Celestron Retrofit Kit)
  
• Celestron RASA 14"

For Celestron SCT Telescopes: Please note that Pegasus provides three different focuser adapters for the SCT range. The difference is in the metal pulley bore diameter & the screw length in the package. Before purchasing please ensure you have selected the correct type.

Please note that some older SCT series are not compatible with the SCT bracket.

Temperature Probe:
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.

Expansion Port / Manual Focus (optional accessory):
FocusCube includes an expansion RJ45 port at the back of the box. This port provides the input for the temperature sensor. An optional hand controller for manual focus control can be acquired separately for those who might want to add this functionality.

ASCOM supported:
The controller is fully compatible with latest ASCOM 6 version.

INDI (Open Astronomy Instrumentation) supported:
Pegasus Focuscube is fully compatible with INDI.

Official INDI Driver available Here

Firmware upgrade support:
Controller firmware supports re-programming via the USB 2.0 connection using upgrade software, for future upgrades which may become available. Pegasus Astro constantly receive feedback from customers and keep updating the firmware and software with new features.

Unity Platform Support:
Pegasus Astro Unity Platform is the new all around application. The goal is to provide a robust and modern application that is going to support current and future Pegasus products under one roof.

A modern frontend allows the full control of all Pegasus Astro devices.
In addition, a REST JSON api helps developers from 3rd party software developers to interact with Pegasus products.
