Sharpstar 2” 0.95X MPCC Coma Corrector Astronomical Accessory for 150mm-600mm Newtonian Reflective Astrographs

Sharpstar 2” 0.95X MPCC Coma Corrector Astronomical Accessory for 150mm-600mm Newtonian Reflective Astrographs

Description:
- Sharpstar 2" 0.95x coma corrector can be applied to most marketable Newtonian reflective astrographs.
- It’s of high quality and easy to use. Sharpstar 2" 0.95x coma corrector is designed for APS-C imaging circles (28mm), suitable for Newtonian reflectors with focal ratio between f/3 and f/6, and aperture size from 150mm to 600mm.
- The reduction factor is 0.95x, thus it can reduce the original f/4, f/5 and f/6 respectively to f/3.8, f/4.75 and f/5.7, effectively shortening the exposure time. Besides, it can improve the star shapes. The diameter of stars in the center of the field can be limited within 10um.

Specification:
- Application: 150-600mm, f/3-3/6 parabolic reflectors
- Reduction factor: 0.95×
- Image circle: 44mm(maximum), 28mm(optimal)
- Lens: triplet structure
- Outer diameter: 50.8mm(2")
- Back focus: 56mm(starting from the field-stop-ring to the focal plane)
- Length: 79.7mm
- Coating: full-surface multi-layer coatings
- Weight: 0.22kg

Package Included:
