Baader Rowe Coma Corrector
The Baader Planetarium RCC-I enables owners of fast Newtonian telescopes to use their instrument for taking stunning wide-field images, or visually, for delivering wide-field views with stars that remain pinpoint to the edge - with no magnification increase!
The RCC-I has been optimized for Newtonians with focal ratios from f/3.5 to f/6, and unlike many correctors has no Barlow-like effect meaning that it does not increase your magnification and image quality is retained. Imaging times stay short and the field isn't narrowed!
The Baader Rowe corrector's triplet lens design has been specifically optimized to be compatible with today's popular CCD and DSLR imaging set ups, working best at a lengthy 91.5mm back-focus. Now there's no need to choose what accessory you leave out of the imaging train, keep your adaptive optics, filter wheels, and guiders in place. For best performance, it is recommended to stay within 3mm +/- of the 91.5mm measurement.
