William Optics M92 Rotator 

William Optics M92 Rotator: 360-degree framing on your 3-inch focuser

The William Optics M92 rotator gives you full control over framing on a 3-inch focuser: you rotate the camera 360 degrees around the optical axis, continuously and without loosening anything. Focusing and alignment remain exact.

The rotator screws in completely via M92 and M83 threads into the train: rigid, tilt-free, and repeatable, exactly what a heavy photographic train on a large apo requires.

Which telescopes

Made for William Optics refractor telescopes with 3-inch focusers, such as the large FluoroStar and GranTurismo models.

Featured accessories

Combine the rotator with the 0.72x reducer-flattener for the large apochromatic refractors: together they form a fully threaded full-frame imaging train.

For whom yes and for whom no

• ✓ Astrophotographers with a WO apochromatic refractor with a 3-inch focuser
• ✓ To be able to choose and repeat compositions exactly
• Owners of 2.5-inch focusers: choose the M63 rotator
