Askar 0.76x Reducer for Askar 80PHQ Telescope
The all new 3" 0.76x Askar full frame reducer is a focal reducer was made specifically for the 80PHQ f/7.5 astrograph. It is a triplet design with 0.76x reduction in focal ratio
The focal ratio is 5.7 with a reduced focal length of 456mm. These lengths work to shorten exposure time cleanly and effectively without decreasing your field of view.
The back focus of this reducer is 55mm, and it has a built-in M48X0.75 filter thread (2") that allows for you to screw your filters on.
This reducer comes equipped with a multi-functioning photographic adapter at the reducer's end. This adapter can be connected to the end thread of the focuser while it is in use.
- We recommend pairing this with the Askar 80PHQ Flatfield Super APO Quadruplet 80mm Astrograph
