Product information

Focus fast, reliable and accurate your telescope using a stepper or DC motor and our controller.

Version3: Same features, more powerful motor outputs,  in a very compact size!

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.

Hint: You can get the controller as a set with our Motor Focus Kit or Motor Focus Kit SCT

Dual mode
The Dual Motor Focus Controller supports two kind of motor types.
  • High Resolution Stepper motors (unipolar and bipolar) for absolute position focusing.
  • DC motors by its Pulse Width Modulation duty cycle control.
Controller can switch motor mode from its software, Mode can be instantly changed (with one mouse click) from stepper to dc motor and saved in controllers 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 telescopes 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 (probe always included in package).

Backlash Compensation
Controller can compensate the backlash you might encounter in your system. Although our motor has very low backlash other setups might need this feature. Backlash compensation is supported from a function inside controllers firmware.

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

INDI (Open Astronomy Instrumentation) compliant
Pegasus DMFC driver is included with libindi >= 1.5.1
Official Indi Driver :

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 constantly receive feedback from our customers and keep updating the firmware and software with new features.

Two Years warranty
Warranty covers the controller device including the temperature sensor.
