Baader RCC coma corrector for Newtonians from f/3 – long 94.5mm distance.
The RCC I (Rowe Coma Corrector) is a new type of Coma Corrector from
Dave Rowe with triplet lens design for Newtonian telescopes from f/3.
This RCC coma corrector offers a long working distance of
91.5mm from the T2 thread, allowing the use of
Long additional parts such as filter wheels, off-axis guiders, etc.
The RCC works great from f/3 to f/6 – works perfectly
he at f/4. The magnification remains unchanged, the focal length
will not be changed.
The coma corrector is retractable and can also be attached to Newton
telescopes that do not have a long focus distance. That
Design is similar to the WYNNE corrector and the image is just as sharp.
