EXTREME 0.78x TRIPLET REDUCER FOR RiFAST & RiLA

$3,299.00

 

Designed from our master optician Massimo Riccardi, this 3 lens design reducer will bring your powerful RiFAst or RiLA telescopes down to f/2.9 and f/4, increasing wide field 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.
