The ZWO F107130RE 0.7x focal length reducer has been developed as a dedicated accessory for the latest ZWO FF107 APO and ZWO FF130 APO astrographs. 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 0.7x, which in the case of the ZWO FF107 APO astrograph gives a value of 524 mm at f/4.9 and for the ZWO FF130 APO model 700 mm at f/5.4. Such parameters allow not only to take breathtaking photos in a wide field of view, but above all significantly shorten the exposure time.

The reducer enables the connection of cameras equipped with M68x1, M54x0.75 and M48x0.75 threads.
