Askar 0.7x Flattener/Reducer for 107PHQ, 130PHQ & 151PHQ
The Askar 0.7x Flattener/Reducer for 107PHQ, 130PHQ & 151PHQ telescopes 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 0.7x reduction factor shortens the focal ratio of the 107PHQ to f/4.9,the 130PHQ to f/5.4 and the 151PHQ to f/4.9, shortening the exposure time and increasing the field of view.
When paired with this flattener/reducer, the focal length of the 107PHQ becomes 524mm, the 130PHQ becomes 700mm and the 151PHQ becomes 740mm, transforming them into extremely capable widefield astrographs. The flattener/reducer has a backfocus requirement of 55mm, making it straightforward to connect common imaging trains.
