Product Details

Building on the massive success of the RedCat 51, William Optics has proudly announced the all-new RedCat 71!

The William Optics RedCat71 is a 71-mm f/4.9 refractor that features a 350mm focal length for fantastic widefield images of the night sky. The optical design is a Petzval design with a doublet front element incorporating FPL-53 glass, plus a single central element and a single rear lens. By using this four-element Petzval design, our WO RedCat71 provides a flat image plane without requiring any additional flattener and the image circle is over 45mm.

WO RedCat71 is designed primarily for imaging, making it an astrograph. This scope provides an excellent color correction and pinpoint stars at the very edge of a 45mm image circle. If you want to take images with the best quality, this beautiful and powerful telescope is what you want.
