Officina Stellare 0.75x Triplet Reducer for RiDK Series
Designed from our master optician Massimo Riccardi, the Officina Stellare 0.75x Triplet Reducer for RiDK Series will bring your powerful f/7 RiDK down to f/5.25, increasing wide field and keeping the same – tiny – star’s shape.
This 3 lens design reducer is fully corrected for a wide field of 42mm. A KAF 1680X chip can be used anyway, with a small amount of vignetting and quality decrease on the extreme borders. It’s fully diffraction limited from 450nm to 730nm.
