RCC I, Rowe Coma Corrector

Description The RCC I (Rowe Coma Corrector) is a Coma Corrector from Dave Rowe with Triplet Lense design for f/4 Newtons The RCC works from f/3.5 to f/6- it is perfect on f/4 Coma Corrector with backfocus 91,5mm reproduction scale is 1:1- in contrast to many other coma correctors, the RCC is no Barlow lens which rely on a magnification to make the larger back-focus to the sensor possible The RCC is the only coma corrector which gives you enough back-focus for filter wheels or other accessories without changing the focal ratio The Baader Planetarium RCC-I (Rowe Coma Corrector) is designed specifically to correct Coma in fast Newtonian imaging systems. The RCC is the ideal match for today's Digital SLRs and CCD Cameras. Long Back Focus: The RCC-I triplet optical design has been optimized to work at a large 91.5mm back-focus distance, enabling the use of Off-Axis Guiders, Adaptive Optics, and Filter Wheels. The RCC even allows users of DSLRs to incorporate off-axis guiding with the Baa
