Focus fast, reliable and accurate your telescope by using the “FocusCube 2″. 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 all of these requirements.
Designed in high quality with modern electronics, FocusCube can provide digital precise focus control from a PC. Device 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 6kg (212 ounces) 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, USB cable, download ASCOM drivers or standalone software and you are ready to go!
FocusCube is a standalone device and includes 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.
Motor can lift up to 6Kg of equipment (212 ounces) of imaging equipment when the telescope points to the zenith!
Two diferent bracket versions
You can choose between:
Universal bracket: which fits to most focusers in the market
Baader Diamond Steeltrack
Explore Scientific Focuser
Skywatcher Esprit Series Focuser
Starlight Feathertouch Series
William Optics GT71
William Optics RedCat
SCT Bracket: SCT Bracket fits to Celestron C Series, Celestron Edge and Celestron RASA telescopes.
We provide three SCT versions. The difference is in the metal pulley bore diameter & the screw length in the package. Please make sure you have selected the correct type!
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.
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.
