Key Features:

F/3.2 Ultra-Fast Optics
Captures deep-sky objects with unparalleled efficiency, utilizing the fastest optical system in William Optics history to maximize photon collection and shorten exposure tracks.

Advanced 7-Element Petzval Design
Provides a naturally flat image field without requiring an additional field flattener, delivering sharp stars and clean detail across a wide imaging area.

43.2mm Full-Frame Image Circle
Supports full-frame, APS-C, and M4/3 camera systems, giving astrophotographers total freedom for wide-field composition and high-resolution deep-sky imaging.

WIFD (William Optics Internal Focuser Design)
The patented internal focusing system keeps the focusing mechanism centered inside the telescope, improving balance and helping avoid rear drawtube-related flexure or vignetting.

Sensor Tilt Xterminator (STX-R)
Features a heavy-duty rear tilt and rotation interface designed to support modern imaging setups, reducing the chance of rear-end sag while retaining convenient sensor-squaring capability.

Anti-Shrink Lens Cell Technology
Helps maintain stable optical alignment under changing temperatures by minimizing the effects of material expansion and contraction around the lens cell.

Built-In Patented Bahtinov Mask
Integrated into the front cap for quick and accurate focusing, making precise star focus easier in the field.

Patented Handle Bar Design
Improves handling, portability, and accessory mounting while maintaining the clean mechanical layout of the Mighty Cat platform.
