The APM Riccardi 0.75x Reducer M82 is a high quality triplet ED reducer/flattener for large apochromatic refractors. It is compatible with many large apo refractors such as APM LZOS triplets which have an M82 x 1 thread, as well as Sky-Watcher Esprit triplets and GSO Ritchey-Chretien telescopes from 10" and larger.
Designed by legendary optical designer Massimo Riccardi, this reducer provides a fully corrected field of 52mm and transforms your telescope into a true astrograph.
The APM Riccardi Reducer features multi-coatings optimized for the spectral range of modern sensors. An optional tilter is available for precise adjustment of the field to optimize star shapes in the corners of the frame.
Note: As this reducer has M82 x 1 threads on both the telescope- and camera-side, additional adapters may be required to attach it to your imaging train.
