Adding a motorized focuser to your telescope makes achieving focus an easy process. The Pegasus Astro Dual Motor Focus Controller will control your Pegasus Astro Motor Focus Kit (sold separately) to achieve focus quickly and accurately, so you can spend more time imaging and observing.

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 controller’s EEPROM memory.

Manual and PC operation.

The controller can be operated by PC using its USB2 connectivity. A manual operation by utilizing 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 Color Indicator

A dual color light emitted diode (Green / Yellow) is fitted on the side of the unit. Each color 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 included temperature 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 very low backlash other setups might need this feature. Backlash compensation is supported from 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 constantly receive feedback from our customers and keep updating the firmware and software with new features.
