Sharpstar 2" 0.95x MPCC Coma Corrector
Sharpstar 2" 0.95x MPCC Coma Corrector
This high-quality Sharpstar 2" 0.95x coma corrector is compatible with most Newtonian reflective astrographs with a focal ratio of f/3 to f/6 and a 150 mm to 600 mm aperture. This handy accessory corrects for coma and ensures sharp images across a 44 mm image field. The design makes this coma corrector easy to use and compatible with APC-C (28 mm) imaging circles. The reduction factor of the coma correct is 0.95x, and can reduce an original focal ratio of f/4 to f/3.8, f/5 to f/4.75, and f/6 to f/5.7, which effectively shortens the exposure time and improves the star shapes.
