Baader MPCC Mark III - Multi Purpose Newton Coma Corrector

The Multipurpose Coma Corrector MARK III (MPCC III) stands out as the sole coma corrector for Newtonian telescopes that preserves the telescope's focal length and field of view.

Traditionally, large aspherical mirrors are favored for deep sky photography due to their wide field of view and superior image brightness. However, these mirrors often suffer from coma and astigmatism, particularly noticeable towards the edges of the field of view. Various coma correctors are available to mitigate these distortions, typically involving lens elements near the telescope's focal point. However, these correctors tend to elongate the telescope's focal length, altering its optical characteristics.

The MPCC III tackles coma effectively without extending the focal length, thanks to its unique 'Phantom Group' multi-coated lens arrangement. This coating ensures optimal light transmission across a broad spectral range, from UV to NIR, maintaining pinpoint star images throughout the field of view. Additionally, the MPCC III is versatile, suitable for both visual observing and photographic applications.

Compatible with most 2" eyepieces and off-axis guiders, the MPCC III offers flexibility in usage. Its 2" stop ring can be removed for deeper insertion into the focuser, allowing for increased back focus.
