Product description:

Designed from master optician Massimo Riccardi, this 4 lens design extender will bring your powerful RiFAst or RiLA telescopes up to f/5.7 and f/7.8, increasing resolution and keeping the same – tiny – star’s shape.

It’s 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
