SharpSky Pro
ASCOM focuser & dew heater controller



(Carl Sagan)
Digital focuser controller
SharpSky Pro is a digital computer controlled focusing solution designed for amateur Astrophotographers and for those who wish to observe. A small rugged controller connects to a motor enclosure housing a small high torque geared stepper motor.  The controller provides both USB computer and manual control at 2880 steps/rev. Manual control is provided by a separate cabled multifunction hand controller. A digital calibrated temperature sensor within the motor enclosure provides feedback allowing temperature compensation and logging features.
ASCOM compliant
SharpSky Pro is fully ASCOM 6SP1 compliant and has been tested with a variety of todays most popular imaging and capture clients.
Digital dew heater controller
SharpSky Pro is also a USB computer controlled four channel dew heater controller housed in the same enclosure as the focuser.  Each channel provides four heater settings which can be customised 0-100% via computer control. The heater controller also generates a clear error indicating a faulty or misconnected heater.
USB computer control
Many of the SharpSky Pro controller features can be adjusted or customised via a computer USB connection. However, care has been taken to allow the controller to operate stand alone.  SharpSky Pro operates out of the box as both a manual focuser and dew heater controller with sensible default settings.
