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 both a Universal (wide) and Newtonian (narrow) black anodized L-shaped aluminum bracket to fit most current focusers.
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.

A must have for successful astrophotography sessions
Focus fast, reliable, and accurate your telescope by using the “FocusCube 2“. The evolution of technology in astronomy requires a system that 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 the temperature can affect the focal length and modify the optimal focus position. Pegasus FocusCube has been developed to meet all of these requirements.

Lifts more than 6kg (13 lbs) of imaging equipment
when telescope point to zenith
FocusCube has a very low backlash and high torque suitable to focus in micron scale.
Due to its high resolution and torque, the FocusCube should be placed on the coarse knob / direct shaft of your telescope focuser
High resolution
Geared Stepper Motor
in an aluminum enclosure
Designed in a high-quality CNC body with modern electronics, FocusCube provides digital precise focus control, for absolute position focusing.
Solid motor couplers in package
Five solid, different bore size, motor couplers are provided so you can select the coupler that fits to your focuser’s shaft. Choose between 4mm to 8mm couplers
Universal Bracket
We have designed the L-shaped bracket to easily fit onto most focusers in the market. The lower part of the redesigned bracket can be replaced with a slimmer rail (included) for better compatibility with Newtonian and other low-profile focusers. This L-shaped black anodized aluminum bracket is hard to bend, has cut rails, and can be attached to a wide range of focusers.
Accurate and repeatable focus v-curves
FocusCube v2 is fully compatible with all modern imaging suites, NINA, SGPro, Voyager, APT. MaximDL etc.
Autofocus by using a v-curve model is a piece of cake operation
V-Curve Results are accurate and repeatable each time the autofocus routine is triggered
A focus run and forget operation
Additional Information
Temperature Probe
An external digital temperature sensor input is located on the side of the focuser. A digital temperature sensor is included in the package. 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.
