APM-LZOS APO-Astrographs

APM LZOS Astrographs

By combining our high-quality Super-ED triplet lenses and ED Doublet systems with specially matched flatteners / reducers, the image plane and the correction in the corners can be further improved. The reducer systems, calculated by Massimo Riccardi, also shorten the focal length by 25% (0.75x). So, extremely fast, world-class refractor astrographs were created.
