Optec Pyxis 2" I.D. Camera Field Rotator

The Pyxis camera rotator was specially designed with the guiding chip of the SBIG ST-x CCD cameras in mind. Simply locate a suitable guide star, enter the position angle and let the Pyxis rotate the camera so that a bright guide star is centered on the tracking chip. For those with alt-azimuth mounts, the Pyxis can derotate the field while tracking the object. A simple Windows interface program is provided that controls rotation and derotation modes as standard. Utilizing a precision sealed 50mm bearing, the Pyxis provides the rigidity and stability you expect from Optec instruments.

Weighing less than 2 lbs the Pyxis can support and rotate the SBIG ST-x line of cameras without slipping. If the holding torque of 27 inch-pounds is exceeded, the drive gear will slip but no damage to the Pyxis will occur. The running torque is 15 inch-pounds. This limit to the holding and running torque will also prevent damage to cables and instruments if a rotational stoppage does occur. The Pyxis can handle the SBIG AO-7 adaptive optic with camera. The clear aperture of the Pyxis is 1.65 inches and adds about 1.6 inches to the back focus. For large instrument packages or systems that use the SBIG STL camera with large CCD, the new Pyxis 3-inch model is suggested.

Intelligent firmware will choose the best direction for each move to keep camera cables from binding. The built-in circuit board provides all the control needed no external hand control box is required. The Pyxis was designed for use with the Optec TCF-S Focuser and IFW filter wheel. Fully compatible with the Optec NextGen MAXfield and NextGen WideField telecompressors, the Pyxis can be used at 1X, 0.5X, and 0.33X using any SBIG camera.
