Baader MPCC Mark III Coma Corrector for Newtonian Telescopes Achieve Sharp, Coma-Free Stars Across the Field The Baader MPCC Mark III is an advanced coma corrector for Newtonian telescopes, designed to eliminate coma and ensure sharpness across the entire field of view without changing your telescope’s focal length or image scale. Ideal for both visual and photographic applications, it performs exceptionally well down to f/3.5, providing pin-sharp stars from edge to edge. Key Features No Focal Length Change: Retains the original focal length and field size, eliminating coma without altering the optical characteristics of your telescope. Vignetting-Free Performance: Works for exposures down to f/3.5 with large lenses, ensuring full illumination for large sensors without vignetting. Maximum Sharpness: Pinpoint stars across the full image field without a central soft spot, even with fast telescopes. Phantom Coating™ Group: Multi-coating for maximum transmission and minimal reflections across a broad spectral range (UV to NIR). Visual & Photographic Versions Available: Photographic Version (2458400A): Removable 2" stop ring collar, works with T-2 (M42) or M48 threads for DSLR cameras. Visual & Photographic Version (2458403): Includes all parts of the photographic version and additional adapters for 1.25" eyepieces, and an adjustable VariLock T-2 extension tube for precise focusing. Photographic Application The MPCC Mark III base element is ready for use with a DSLR and a standard T-ring, suitable for T-2 threads on most T-rings. For larger sensors, the T-2 thread can be removed, and the M48 thread provides a larger aperture, ensuring full illumination even for full-frame sensors. Compatible with Canon EOS T-rings with an optional M48 spacer ring. Visual Application The MPCC Mark III provides sharp, coma-free views for visual astronomers. The V-1 Set (2458403) includes all the necessary adapters for 1.25" eyepieces, and the VariLock extension tube allows for precise adjustments to achieve optimal focus.
