  Mini-Sextant Tracking Mount

The Mini-Sextant Tracking system is a high-performance TSPI data gathering platform designed to accommodate 12” to 20” aperture optical assembly in an on-axis configuration.   The Mini-Sextant azimuith trunion is fabricated from high strength aluminum alloy for structural rigidity and stability.

A tertiary mirror in the optical path to direct light out to an instrument platform to the side of the center mounted optical assembly.  Multiple sensors/cameras can be accommodated on the side platform with the use of a dichroic beam splitter.  Photo-Sonics also offers a coude path configuration where the light beam can be directed down through the mount to an optical workbench.  This optical workbench can be enclosed for weather and environmental protection.  On the opposite side is supplemental payload platform for additional instrumentation.  The supplemental side platform has removable payload shelves that can be positioned to fit the dimensions of the sensors.  Up to four mounting positions can be configured.  Typically acquisition and tracking sensors/lenses/laser rangefinder will be configured here.  Another use is for spectral coverage outside of the main telescope, such as the addition of a Mid Wave Infrared Sensor / dewer / optics.

  
       
 

Three powerful direct-drive DC torque motors for high dynamic performance and is offered in both fixed and mobile configurations.  Photo-Sonics manufactures custom trailers with integrated electronics and a four jack stabilization system.

The Mini-Sextant uses the Photo-Sonics digital servo amplifier with the same common architecture incorporated in our other mounts, and the Argus Tracking and Instrument Control System.  A remote control console is offered with video switching matrix, stiff stick, foot pedals, custom switches and controls for complete remote operation of the mount.  The Argus certified instrument suite available on other Photo-Sonics tracking systems is also available for the Mini-Sextant.
