Ultra Flat 132 (0.79x Reducer)

Description

The William Optics Ultra Flat 132 is a 0.79x focal reducer and field flattener designed for compatible William Optics telescopes. It reduces the focal length by 21%, producing a faster focal ratio and wider field of view while correcting field curvature across the entire image plane. This results in sharp, round stars from center to corner on full-frame sensors. An essential optical accessory for serious deep-sky astrophotography.
