ZWO 0.76x REDUCER FOR FF80 is backordered and will ship as soon as it is back in stock.
The 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 widefield astrograph. The flattener/reducer has a backfocus requirement of 55mm, making it straightforward to connect common imaging trains.
