William Optics Pleiades Astrographs

William Optics Pleiades astrographs are seven-element refractors designed for flat, well-corrected fields in deep-sky imaging. The line covers three sizes: the Pleiades 68 at f/3.8 for very wide fields, the Pleiades 111 at f/4.8 with WIFD internal focusing, and the Pleiades 181 at f/5.5 with three ED glasses.

They suit imagers who want a fast, integrated optical design instead of a refractor plus a separate flattener or reducer.
