*Stepper Motor Focus Standard

• Pegasus Astro Stepper Motor Focus Controller

Focus fast, reliable and accurate your telescope using a stepper motor and this controller. 

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 Stepper Motor Focus Controller (SMFC) has been developed to meet these requirements. 

Designed in high quality with modern electronics it can provide digital precise control of compatible motor focusers from a PC. SMFC is suitable for astro-photographers.. It can drive unipolar stepper motors for absolute position focusing. SMFC designed in a very compact size and weight. Suitable to attach it near your telescope mount plate. 

• Compatible DB9 connector pin out

Motor output is fully compatible with “Robofocus or Moonlight Motors” pin out.

• Temperature compensation

An external digital temperature sensor input is located near the motor connector. The digital probe of length of one (1) m 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

• ASCOM support

The controller is fully compatible with ASCOM 6.
