Focus your telescope fast, reliably and accurately using the “FocusCube 2″. Fast optics and modern camera devices require automatic focusing. As temperature changes can affect focal length and modify the optimal focus position it is necessary to refocus as the temperature changes or at regular time intervals. Pegasus FocusCube has been developed to meet these requirements.
High quality mechanical and electronic design allows the FocusCube to provide precise digital focus control from a PC. The device includes a stepper motor for absolute position control. Both the electronic controller and stepper motor are enclosed in a compact sized box.
Attach the FocusCube to your refractor, reflector or SCT telescope, plug in the power, connect the USB cable, download the ASCOM drivers or standalone software and you are ready to go!
- FocusCube 2 is a standalone device that includes the controller functionality.
- No 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 this RJ45 port to the Ultimate Powerbox RJ45 Stepper Output
- The RJ45 port at the back is only for the hand controller or the included temperature sensor.
High torque & resolution stepper motor
Embedded unipolar stepper motor has a powerful and very low backlash gearbox. Motor Step Angle is 7.5 deg but the 1:120 reduction gearbox turns the reduction rate to 0.06255 deg / step. As firmware implements half step drive, the motor can execute twice the steps per cycle. This means 11510 steps per cycle! Bottom line: You can focus in microns, easily and with great accuracy.
In addition the motor can lift up to 6Kg of equipment (212 ounces) of imaging equipment when the telescope points to the zenith!
Universal bracket fits the following focusers
- Baader Diamond Steeltrack
- Baader Steeltrack
- Explore Scientific Focuser
- Moonlite Focusers
- Skywatcher Esprit Series Focuser
- Starlight Feathertouch Series
- Stellarvue Focusers
- Takahaski Focusers
- Vixen ED815
- William Optics GT71
- William Optics Red Cat
An external digital temperature sensor input is located near the motor connector. A digital probe of one meter (3 feet) 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)
Expansion Port / Manual Focus (optional accessory)
FocusCube includes an expansion RJ45 port at the back of the enclosure. This port provides input for the temperature sensor. An optional hand controller for manual focus control can be acquired for those who might want to add this functionality.
Please Notice: Hand Controller is an optional accessory
The controller is fully compatible with latest ASCOM 6.4
INDI (Open Astronomy Instrumentation) supported
Pegasus Focuscube is fully compatible with INDI. Driver is included in stable libindi.
Official Indi Driver : http://indilib.org/devices/focusers/pegasus-dmfc.html
Standalone program supported
The controller can be operated by the standalone software.
(Only available for Windows)
All required cables are included
- A 1.8m USB Type B cable
- A 1.5m Cigarette lighter adapter power cable
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 “Universal” package.
Firmware upgrade support
Controller firmware supports re-programming via the USB 2.0 connection using upgrade software, for future upgrades which may become available. We constantly receive feedback from our customers and keep updating the firmware and software with new features.
