The Sharpstar 50EDPH 0.84x reducer was developed as a dedicated accessory for the Sharpstar 50EDPH astrograph. It guarantees excellent field correction, thanks to which it works perfectly with cameras and camcorders equipped with an APS-C format matrix.

This reducer reduces the focal length by a factor of 0.84x, which in the case of the Sharpstar 50EDPH astrograph gives a value of 230 mm at f/4.6. Such parameters allow not only to take breathtaking photos in a wide field of view, but above all to 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 camera side.
