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.
