The ASA 2" Reducer Corrector for Newtonians was designed by Dipl Phys. Philipp Keller and has a multiplier of 0.73x meaning an F4 Newtonian will become F2.9 with a 0.73x reduction in focal length.

The back focus of the reducer is typically 65mm depending on the F ratio of the scope it is partnered with, at which point it offers a corrected field of 20mm.  This allows an almost fully illuminated image field with the popular 8300 sensor and some vignetting when used with APS sized sensors.
