William Optics - Redcat 51 F/4.9 Petzval Refracting Telescope with WIFD - Version 3

The William Optics RedCat 51 refractor telescope features a 51mm objective lens, in a sleek quadruplet Petzval APO design, using Synthetic Fluoride (FPL53 and FPL51) glass for a full frame flat field image. The optical quality provides a fast focal ratio of f/4.9, 250mm focal length. The William Optics RedCat 51 will out resolve most high resolution DSLR lenses of similar focal lengths with exceptional color and contrast.  The version 3 consists of WIFD internal focusing.

The version 3 of the Redcat 51 consists of WIFD internal focusing. Included with the RedCat 51 is a convenient soft carry case, removeable dew shield, M48 camera adapter, and William Optics patented Bahtinov mask cap. The William Optics RedCat 51 Petzval telescope is ideally suited to night sky astrophotography, wide field astroimaging, and wildlife photography.

True Fluorite is a rare mineral which create very expensive optical lenses. Being a natural material, consistency and impurities are additional factors which further increases cost as does the cost of mining and the impact on our environment. Synthetic fluorite is a highly stable monocrystal completely free of impurities. It does not emit fluorescence in UV light and is an extraordinarily clear lens material. Great care is taken during manufacturing for grinding and polishing this material to ensure that the lens does not chip or scar, and the result is a lens that is completely free of chromatic abberation making it ideal for astrophotography and wildlife imaging or viewing.

WIFD Patented Internal Focusing Design from William Optics

A major favorable value to the Redcat 51 Version 3 is William Optics patented WIFD internal focusing system. This is preferred for imaging because there is no obstruction that is typically caused with rear focusers that are external. As a result, all the focusing takes place internally inside the optical tube which in addition to having a slicker appearance, reducing vignetting risk and unwanted shifts and jolts which can cause misalignment of the elements
