PerfectStar Focus Motor for SCT

The PerfectStar Focus Motor for SCT is designed to provide precise control of focus with Schmidt-Cassegrain Telescopes (SCTs).  Although intended specifically for use with the PerfectStar Focus Controller, the motor is also compatible with controllers from many other manufacturers.   The standard mounting for the PerfectStar motor works well for most refractors and Newtonian reflectors, but required customization to work with the typical SCT focus mechanism, which works by moving the primary mirror rather than moving a draw tube.  With the PS SCT Motor it is now very easy to install a focus motor on an SCT. The motor is […]


PerfectStar Focus Motor

The PerfectStar Focus Motor is a premium stepper motor designed to provide precise control of focus with many types and models of telescope.  Although intended specifically for use with the PerfectStar Focus Controller, the motor unit is also compatible with controllers from many other manufacturers.   Based on a top-quality stepper motor from Hurst, it provides the reliability and precision needed for demanding astrophotography applications. The motor is enclosed to protect the motor from dust and moisture. Likewise, the aluminum mounting collar encloses the focuser shaft (and reduction mechanism where present) to prevent dust from getting into this sensitive mechanism. […]


PerfectStar Focus Controller

With version 5.0 of the firmware and version 6.0 of the ASCOM driver, PerfectStar is now completely updated. Most functionality is now embedded in the controller itself rather than the driver, which makes it more robust and allows access to many features without a computer connection. The absolute position value is maintained in the controller – even when powered off.  The hand controller (now standard) is used to toggle temperature compensation, set the zero point, report the current position, and prepare for focuser lock and shutdown.  A new double speed mode provides faster rough positioning, which is very useful when […]
