The Pegasus Astro Dual Motor Focus Controller (DMFC) is a perfect match for visual astronomers and astro photographers. The DMFC V3 supports full manual and digital operation for imaging or visual use. It's fully PC ASCOM compliant and the drivers are VERY easy to use and install compared to most focuser systems. This is the new version 3 model - same features, more powerful motor outputs but in a compact size!
The "Premium Kit" package - a complete focus system, ready to install and operate on your specific telescope/focuser contains:
  • Dual Motor Focus Controller
  • Power Cable with 12V Car Lighter socket plug.
  • Temperature Sensor 1m length
  • High Resolution Stepper Geared Motor (Step Angle 7.5, Deg 120, Gear Ratio 1:120)
  • Universal Black Anodised Thick Aluminium Bracket for Motor (does not bend) including fixing hardware.
  • Motor Coupler (4mm to 8mm shaft OD) 3 screws ensure that you will securely lock (on axis) to different shaft diameters.
  • Serial Cable for Stepper motor (1.5m)
  • USB type B cable

Dual Motor Focus brings a decade of experience in astrophotography and telescope focusing concepts. 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 Dual Motor Focus Controller (DMFC) has been developed to meet these requirements.

The Dual Motor Focus Controller supports two kind of motor types.
  • DC motors by its Pulse Width Modulation duty cycle control.
  • High Resolution Stepper motors for absolute position focusing.
Controller can switch motor mode from its software, Mode can be instantly changed from ‘stepper’ to ‘dc’ motor and saved in controller’s EEPROM memory

Manual and PC operation
The controller can be operated by PC using its USB2 connectivity. A manual operation by utilising the digital encoder on the side of the controller simulates the knob of your real focuser. Turn the knob as it is the knob of your telescope’s focuser. If you press it, speed of the motor will be reduced to 1:10.

Dual Colour Indicator
A dual colour light emitted diode (Green / Yellow) is fitted on the side of the unit. Each colour indicates speed and the led can be turned on or off by its software during an observing session. Keep it pressed to disable the knob.

Robofocus compatible connector pin out
Motor output is fully compatible with “Robofocus ©” pin out. Output can drive most of the motors in the market. Take a look in our F.A.Q tab.

Temperature Probe
An external digital temperature sensor input is located near the motor connector. A digital probe of one (1) meter 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.
Backlash Compensation

Controller can compensate the backlash you might encounter in your system.Although our motor has nearly zero backlash other setups might need this feature. Backlash compensation is performed in a function inside controller’s firmware.

ASCOM compliant
The controller is fully compatible with latest ASCOM 6 and can easily be controlled from a computer.

Standalone program support
The controller can be operated by the standalone DMFC software. (Only available for Windows OS)

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 are listening our customers and keep updating the firmware with new features.

One Year warranty
Warranty covers the controller device including the temperature sensor and the Pegasus Stepper Motor kit.
