Coma Corrector for Newton telescopes, that neither does reduce the focal length nor the image field of your telescope, 46 mm clear lens diameter in M48 mode enables exposures free from vignetting. Designed for fast f-ratios up to f / 3.5. Maximum sharpness across the entire image field. Phantom Coating Group, multicoated for maximum transmission and total freedom from reflections.

However this comes at the price of off axis coma and some residual astigmatism. Coma will distort off axis stars into "comets" which effectively reduces the usable field considerably. Many companys offer various lens systems as solution to counteract coma, most at the downside of increasing the original focal length and reducing the field of view. An f4 optics may become an f4.5The Multi Purpose Coma Corrector Mark III eliminates coma across the full photographic field without manipulating the focal length. The proprietory lens design has our Phantom Group wideband multicoating on all air to glass lens surfaces. This treatment delivers highest transmission combined with lowest amount of scatter and reflections across a very wide spectral range from UV to NIR. The original MPCC had been designed for an f/ratio of f4.5 to f6. The new Mark III however works exceptionally well even down to f3.5. Stars remain pinpoints across the field and the visual use likewise is made much easier - with the help of the 2" (M48) male filter thread at the eyepiece facing side.MPCC Mark III Technical data no change in focal length or field size, an f4 Newtonian remains f4. newly calculated lens system - designed for an unvignetted field down to f3.5 maximum sharpness across the field - without center soft spot (as reported of other) accepts T-2(M42x0.75) and/or 2"(M48x0.75) threaded photographic- or visual-adapters 2" stopping collar removable for increase in backfocus For photographic and visual use easy to use exceptional price/performance ratio Phantom Group multicoated for maximum transmission and freedom from reflections from UV to NIR
