About this product
The Askar new 3 inch 0.76x full frame Focal Reducer.
The new Askar 3 inch 0.76x full frame reducer, features a triplet optical design and has been introduced specifically for use with the 80PHQ Telescope.
It provides a focal reduction of 0.76x reducing the focal ratio from F7.5 to F5.7 and a reduced focal length of 456 mm.
Thus effectively shortening the exposure time and dramatically increasing your field of view and allowing the astro imager to capture more data in a shorter period of time.
Located Focuser side is the multi-functional four-piece photographic adapter, which can be connected to the end thread of the focuser. The backfocus is the standardised 55mm and the Reducer also has a built-in M48X0.75 (2 inch) filter thread that allows you to screw on filters conveniently.
