Astrophotography accessories 0.7x Focal Reducer Lens For 925 OTA #94245 C9.25HD

A 60mm clear aperture is optimized for larger full-frame sensors to avoid vignetting of the scene. The reducer maintains the optic's flat-field through the use of a 4-element lens using Lanthanum glass, with blackened edges, and anti-reflection fully multi-coated optics. Designed specifically for their 9.25" optical tube assembly (OTA), the 0.7x Focal Reducer Lens speeds its focal ratio from an f/10 to a much faster f/7.1 for drastically reduced exposure times.
