Focus fast, reliable and accurate your telescope by using the “FocusCube

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 these requirements.

Designed in high quality with modern electronics it can provide digital precise focus control from a PC.

FocusCube 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 4kg 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 and a USB cable, download ASCOM drivers or standalone software and you are ready to go!


FocusCube is a standalone device and includes controller functionalityNo 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 its RJ45 port with the Ultimate Powerbox RJ45 Stepper Output
The RJ45 port on the left is only for external accessories and for the temperature probe.

Temperature Probe

An external digital temperature sensor input is located near the motor connector. A digital probe of one (1) meter 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 in the package)


Six solid motor couplers are included

Six solid, different bore size, motor couplers are provided so you can select the coupler that fits to your focuser’s shaft. Choose between 3mm to 8mm couplers. All of them are included in the package.
