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!
