reliable and accurate your telescope using a stepper or DC motor and
our controller. This controller will only control one motor.
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
Installation services can be provided by Ontario Telescope and Accessories. Ship your focuser or Telescope to use and we will install and test the stepper on your focuser. You focuser or Telescope will be shipped back to you and is included in the service cost.

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
Manual and PC operation.
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 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.

motors in the market. Take a look in our F.A.Q tab.
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
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.
