Pegasus FocusCube 2 with Universal Bracket

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.

Featuring a superior quality design with modern electronics, the Pegasus FocusCube offers precise digital focus control via a PC. These electronics, along with a stepper motor that enables absolute position focusing, are housed in a small, compact box. But don't be fooled by its size! This device is capable of lifting imaging equipment weighing more than 6 kg (13.2 lbs.) without difficulty when the telescope is pointed towards the zenith!

Includes a Universal L-Bracket that fits most current focusers. An SCT Bracket version for Celestron C series, EdgeHD, and RASA telescopes is also available, but not included.

Make sure you choose the correct bracket that will fit your needs.

High Torque & Resolution Stepper Motor

The embedded stepper motor is a high resolution geared stepper motor. Its powerful gearbox has very low backlash and high torque suitable for focusing in micron scale easily and with great 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. As firmware implements half step drive, the motor can execute twice the steps per cycle. This translates to 11,510 steps per cycle! Simply attach the FocusCube to your refractor, reflector, or Schmidt-Cassegrain telescope, plug in the power and USB cables, download the ASCOM drivers or independent software, and you'll be ready to begin.

Please Note : The FocusCube is a standalone device and does not require a hand controller. It should not be paired with the Dual Motor Focus Controller or any other controller on the market. The RJ45 port should not be connected to the Ultimate PowerBox RJ45 Stepper Output.

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.

The Pegasus Astro FocusCube is compatible with ASCOM 6.4 and INDI (Open Astronomy Instrumentation

Firmware Upgrade Support

Controller firmware supports re-programming for forthcoming upgrades via the USB 2.0 connection and upgrade software. Pegasus Astro is constantly adding new features to both the firmware and the software based on customer feedback.
