ZWO 0.76x REDUCER FOR FF80 CELESTRON-IP The filter cell is threadedThe ZWO 0. 76x Flattener Reducer for the FF80 is a 3" corrector for full frame sensors. The flattener reducer is a triplet design with one element of ED (Extra low Dispersion) glass. The 0. 76x reduction factor shortens the focal ratio of the FF80 to f 5. 7, shortening the exposure time and increasing the field of view. When paired with this flattener reducer, the focal length of the FF80 becomes 456mm, transforming it into an extremely capable
