Askar 0.76x Reducer for the 80PHQ 

The Askar 0.76x Flattener/Reducer for the 80PHQ 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 80PHQ 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 80PHQ 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.

The Askar new 3 inch 0.76x full frame reducer,with a triplet design and specifically for the 80PHQ, offers a 0.76x reduction in focal ratio, when used with the 80PHQ F/7.5 astrograph,the focal ratio is 5.7, and the reduced focal length is 456 mm, effectively shortening the exposure time and dramatically increasing your field of view and bringing more convenience and possibilities for your deep-sky astrophotography.
