Pegasus FocusCube V2 for SCT, Edge & RASA
Focus fast, reliable and accurate your telescope by using the Pegasus FocusCube V2 for SCT, Edge & RASA. The evolution of technology in astronomy requires a system which will assist the focusing of the telescope with great accuracy. Fast optics and modern camera devices require automatic focusing in every small period of time as temperature can affect focal length and modify the optimal focus position. Pegasus FocusCube has been developed to meet all of these requirements. Designed in high quality with modern electronics, FocusCube can provide digital precise focus control from a PC. Device includes a stepper motor for absolute position focusing. Electronics and stepper motor are enclosed in a compact sized box. Do not be fooled by its size! This device can easily lift more than 6kg(212 ounces) of imaging equipment when the telescope points to the zenith! This stepper motor is a high resolution geared stepper motor (Step Angle 7.5, Deg 120, Gear Ration 1:120). Its gearbox has very low backlash and high torque suitable to focus in micron scale! You only need this device to focus! Attach the FocusCube to your refractor / reflector / SCT telescope, plug the power, USB cable, download ASCOM drivers or standalone software and you are ready to go!
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.
The SCT Bracket fits to Celestron C Series, Celestron Edge and Celestron RASA telescopes. Please notice
: We provide three SCT versions. The difference is in the metal pulley bore diameter & the screw length in the package.
- Celestron Classic/ Edge 6, 8, 9.25” & RASA 8” -> bore 13mm
- Celestron Classic/ Edge 11” -> bore 22mm
- Celestron Classic/ Edge & RASA 14” -> bore 22mm
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.
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 always included)
Expansion Port / Manual Focus (optional accessory)
FocusCube includes an expansion RJ45 port on the left side. 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.
Autofocus via SGPro
Unity Platform Support
Firmware upgrade support
Controller firmware supports re-programming via the USB 2.0 connection using upgrade software, for future upgrades which may become available. We constantly receive feedback from our customers and keep updating the firmware and software with new features.
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.
