Pegasus FocusCube 2 with Bracket
for Celestron 6" - 9.25" SCT, 8"-9.25" EdgeHD & 8" RASA Telescopes

The Pegasus Astro FocusCube is a dependable fast and accurate telescope focusing system that has kept up with constantly evolving astronomy technology in order to assist fast optical systems and modern imaging cameras in providing the precision focusing they require. These contemporary camera devices necessitate automatic focusing following only a tiny period of time since temperature can influence both focal length and optimal focus position. Pegasus has developed the FocusCube to meet all of these requirements.

For precise digital focus control using a PC, the Pegasus FocusCube with its high quality design and state-of-the-art electronics, is an effective solution. Along with a stepper motor that allows absolute position focusing, these modern electronics are housed in a small, compact enclosure. However, despite its diminutive size, this device is easily capable of lifting over 6 kg (13.2 lbs.) of imaging equipment when the telescope is pointed towards the zenith!

Includes a bracket for 6", 8", and 9.25" Celestron SCT, 8" & 9.25" EdgeHD, and 8" RASA telescopes. A Universal L-Bracket version is also available.

Please note that the FocusCube 2 works with the Celestron Edge HD scopes when the 0.7x focal reducer is installed.

High Torque & Resolution Stepper Motor

A high resolution geared stepper motor is incorporated into the Pegasus FocusCube. With very low backlash and high torque, the FocusCube is able to easily focus in micron scale with a high level of accuracy. Motor step angle is 7.5 degrees, but with a 1:120 gear ratio, the gearbox reduction rate is 0.06255 degrees per step. And, with firmware initiated half step drive, the motor is able to execute twice the steps per cycle for 11,510 steps! Once you’ve attached the FocusCube to your refractor, reflector, or SCT, plugged in the power and USB cables, and downloaded the ASCOM drivers or standalone software, you’ll be all set to begin using the device.

Temperature Probe

Located near the motor connector is an external digital temperature sensor input. This input accepts the included one (1) meter long digital probe that can be placed near the focuser so that the precise temperature of the focuser/environment can be determined through the provided software or ASCOM driver.

Firmware Upgrade Support

Any upgrades that become available at a future date will be supported by reprogrammable controller firmware and delivered using a USB 2.0 connection and upgrade software. Pegasus Astro regularly updates their firmware and software with new features based on the constant feedback from customers they receive.
