William Optics REDCAT 71 mm f/4.9 Astrograph
The William RecdCat 51 is a successful model and has found its following. Now William offers the much more powerful RedCat with 71 mm aperture. The refractor is again designed for mobile astrophotography and is carried by smaller mounts or by stable startrackers.

The apo is aimed at astrophotographers and nature photographers who are looking for a portable and powerful manual telephoto lens. The focusing is like with a telephoto lens via a knurled ring. The Pezval design offers a very good correction and illumination for all cameras up to full frame format.

Photography with the RedCat 71 apo:
Astrophotography: With 348 mm focal length and fast f/4.9, short exposure times are possible. The working distance of 55 mm allows the use of all common astro cameras, system cameras and DSLR/SLR cameras. The use of nebula filters is also possible due to the 2" filter thread integrated in the helical focuser. Included is a Bahtinov mask for astrophotography. The mask helps with focusing and is integrated in the objective cap.
Countryside photography and animal photography: The RedCat 71 is also perfect for, for example, photographing animals. The slip-proof helical focuser allows focusing within seconds. The image quality will impress you. A photo tripod is necessary for use.
