Skywatcher 2" Coma Corrector for Newtonian Telescopes - perfectly suitable for DSLR cameras
The Skywatcher coma corrector is optimized for all Newtonian telescope with a focal ratio of f/6 to f/4.5 and a 2" focuser. The corrector is suitable for photography and observing. It corrects the Newtonian coma and provides pinpoint stars to the edge.

The advantages of the Skywatcher coma correctors:
Versatile - usable for photography and for observing
Better illumination due to the M48 thread - illuminates even large sensor diameters
M48 adapters for DSLR available
Very good multi-coated optics for maximum sharpness without annoying reflections
