Welcome Cat71 to join WO Cat family!!!

The WO Cat71 is a 71-mm f/4.9 refractor using a Petzval design with a doublet front element incorporating FPL-53 glass, plus a single central element and a single rear lens. By this design, our WO Cat71 provides a flat image plane without any additional flattener and the image circle is over 45mm. WO Cat71 is designed primarily for imaging, making it an astrograph.

This scope provides an excellent colour 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.
