William Optics RedCat Telescopes

William Optics RedCat telescopes are small Petzval apochromats known for wide-field astrophotography with a DSLR, mirrorless or astronomy camera, with a flat field built into the design. The RedCat 51 is available as the Gen II U f/4.9 and in a WIFD version with internal focusing.

The RedCat 61 WIFD and RedCat 71 WIFD offer more aperture for the same grab-and-go format. A 1.25" RedCat WIFD erecting prism turns the scope into a correct-image spotter for visual use.
