## Summary description

Beta MPCC Mark III Photo + Visual 2" coma corrector reduces off-axis coma in reflector telescopes for both photographic and visual use. Designed to fit 2-inch focusers, it improves star shapes across the field, yielding sharper stars and better image quality at wide fields. Suitable for astrophotography and visual observing where edge-to-edge performance matters.

## Long description

The Beta MPCC Mark III Photo + Visual 2" coma corrector is an optical accessory for reflector telescopes that reduces off-axis coma and improves star shapes across the field. Designed for 2-inch focusers, this corrector delivers sharper stars and more uniform image quality toward the edges of the field, making it suitable for both photographic and visual observing. It maintains parfocality with visual eyepieces and photographic cameras when used with appropriate adapters and spacing.
Advantages
The design corrects coma while preserving the native focal ratio of the telescope, enabling wide-field imaging without excessively changing exposure requirements. Improved edge sharpness reduces star elongation and simplifies image processing for astrophotography. Mechanical compatibility with standard 2" focusers and a parfocal visual path allow quick switching between camera and eyepiece use without significant re-focusing.
Suitable for
 Wide-field astrophotography with reflector telescopes
 Visual observing where round stars across the field are desired
 Amateur astronomers using 2" focusers and DSLR or dedicated astronomy cameras
 Observing and imaging with Schmidt-Newtonian and fast Newtonian reflectors
Key specifications
 Optical function: coma correction for reflector telescopes
 Focuser interface: 2" (standard) mechanical mounting
 Use modes: photographic and visual (parfocal with proper spacing)
 Field performance: improves star shapes toward the edge of the field
 Compatibility: designed for fast focal ratios commonly used in wide-field setups
How to use
Install the coma corrector into the telescope's 2" focuser and secure it according to the focuser's locking mechanism. Attach the camera adapter or visual eyepiece to the corrector; for photographic use, ensure the recommended spacing between the corrector and the camera sensor is observed to achieve optimal correction and focus. When switching between camera and eyepiece, minor focus adjustments may be required depending on camera backfocus and adapter thickness.
Usage recommendations
To achieve best results, verify the correct backfocus distance for your specific camera and adapters before a long imaging session. Use a Bahtinov mask or focus aid to obtain precise focus, and perform flat-field calibration in post-processing to correct vignetting or residual field illumination variations.
