ZWO 0.75x REDUCER FOR FF65 polemaster mechanical errors can minimized throughThe ZWO 0. 75x Flattener Reducer for the FF65 is a 2. 5" corrector for full frame sensors. The flattener reducer is a quadruplet design with one element of ED (Extra low Dispersion) glass. The 0. 75x reduction factor shortens the focal ratio of the FF65 to f 4. 8, shortening the exposure time and increasing the field of view. When paired with this flattener reducer, the focal length of the FF65 becomes 312mm, transforming it into an extremely capable
