The Pyxis 3" Rotator is a larger and more powerful counterpart to the Pyxis 2", designed to hold large instrument packages without any flex or wobble. With a resolution of 0.01875 degrees per step, rotation of the central tube or derotation of long-exposure Alt-Az images will pose no problem to this instrument.

The Pyxis 3-inch has a full 3 inches of clear aperture and is designed to hold large instrument packages without flexure or wobble. 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. The Pyxis 3" is compatible with the Optec Alt-Az derotation server allowing for full derotation support. Power requirements and other operating conditions are similar to the 2-inch Pyxis model.
