    Optec Pyxis 3" Generation 2 Field Rotator for AstroPhysics 3.5"

    The Optec Pyxis 3" Generation 2 Camera Field Rotator has a full 3 inches of clear aperture and designed to connect specifically to Astro Physics 3.5" drawtubes.

    Designed to hold large format imaging set ups without sacrificing available field of view. The Optec Pyxis Field Rotator offers stability and strength to ensure heavy imaging set ups can be carried without wobbling or flexure. Included is the appropriate adapter to attach to your AstroPhysics telescope with a 3.5" opening and will easily mate with the Optec 3" Temperature Compensating Focuser. A 15VDC regulated power supply is included with a right angle 2.5mm power jack. The use of a 15V power supply allows approximately 20% more torque than 12V, without sacrificing speed. Full computer control is possible with the included PYXIS.exe software or your choice of 3rd party compatible software.

    De-rotation of the field is a necessary correction for extended exposure astrophotography on an alt-azimuth mount. Stars remain perfectly round and stable. A 6 inch bronze worm gear and stainless worm rotate the center tube with a resolution of 0.01875 degree per step from the stepper motor. Motion is perfectly smooth, even and stable. Due to the large format of this field rotator and a thickness of 2.4", it is intended for use with heavier telescopes with medium to heavy duty mounts as the added weight could have an effect on the mount's performance.
