Product Description & Reviews

Achromat owners rejoice! Baader Planetarium has taken minus violet filtration to a new level. The Fringe Killer brings a type of filtration never before seen to the amateur. Rather than simply trimming the shorter wavelengths at a chosen wavelength and slope like all other minus violet filters the Fringe Killer carefully attenuates a specific region of the spectrum. This allowed Baader to tune the filter for maximum practical reduction of the most damaging defocused blue wavelengths with only a faint yellow color shift - without dimming and lowering image contrast by resorting to reduction of the important green-yellow wavelengths to crudely restore an apparent color balance! (where the eye is very sensitive and where refractors are their sharpest) The result is a filter that removes the majority of color fringe without affecting image brightness all imparting strong coloration or reducing contrast at important wavelengths. As any telescope owner knows light is a valuable commodity for both planetary and deep sky viewing and the fringe killer preserves every bit of light possible. Terrestrial observers will also find the qualities of this filter to be ideal for their needs.The high quality of Baader Planetarium filters permits stacking with no image degradation. For an even less colored view with noticeably boosted color contrasts we highly recommend stacking a Moon & Skyglow filter with the Fringe Killer. These two filters complement each other and the result is an almost totally neutral view (no coloration). Image brightness is also very minimally affected due to the optimized formula of the Moon & Skyglow along with the superb anti reflection coatings.For two recent user reviews of the Fringe Killer please see Cloudy Nights at: The Fringe Killer is the perfect compliment to the Baader Contrast Booster. The Contrast Booster is an aggressive filter designed to deliver the maximum sharpness and contrast possible from an achromat.
