The ZWO F65RE 0.75x reducer has been developed as a dedicated accessory for the latest ZWO FF65 APO 65 mm astrograph. It guarantees excellent field correction, thanks to which it works perfectly with professional cameras and camcorders equipped with a full-frame matrix.

This reducer reduces the focal length by a factor of 0.75x, which in the case of the ZWO FF65 APO 65 mm astrograph gives a value of 312 mm at f/4.8. Such parameters allow not only to take breathtaking photos in a wide field of view, but above all significantly shorten the exposure time.

This device allows the installation of filters with a diameter of 2", screwed into the M48x0.75 thread on the side of the camera.
