Sharpstar CRC2095 Coma Reducer Corrector

The 2″ Sharpstar 0.95x coma corrector can be applied to most marketable Newtonian reflective astrographs. It’s a high quality product and it’s easy to use. The coma corrector is designed for APS-C imaging circles (28mm), suitable for Newtonian reflectors with focal ratios between f/3 and f/6, and aperture size from 150mm to 600mm.

Due to the reduction factor of 0.95x, the coma corrector can reduce the focal ratio from f/4, f/5, and f/6 to f/3.8, f/4.75, and f/5.7. Effectively shortening the exposure time. Also, it can improve the star shapes. The diameter of stars in the center of the field can be limited within 10um.
