Baader 2" Fringe Killer Telescope Filter





The Baader Planetarium Fringe Killer Telescope Filter is a great filter for achromat owners. Baader has taken minus violet filtration to a new level with this filter. The Fringe Killer brings a type of filtration, never before seen, to the amateur astronomer. Rather than simply trimming the shorter wavelengths at a chosen wavelength and slope like all other minus violet filters, the Baader Planetarium Fringe Killer carefully attenuates a specific region of the spectrum. This allowed Baader to tune the filter for maximum practical reduction of the worst defocused blue wavelengths, with only a faint yellow color shift, without dimming and lowering image contrast. This is a 2" filter.




The result is a filter that removes the majority of color fringe, without affecting image brightness, 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 Baader Planetarium Fringe Killer Telescope Filter preserves every bit of light possible. Terrestrial observers will also find the qualities of this filter to be ideal for their needs.




The coatings required to accomplish this innovative filtration are exceedingly complex, requiring almost 50 layers per side, using the latest DWDM Plasma assisted coating process. The Baader Planetarium 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. The result is complete removal of the violet haze, with a somewhat dimmer and yellow color image. The Contrast Booster also incorporates additional RGB filtration for further enhancing color contrasts. The Fringe Killer provides a milder more natural filtration, that leaves fast achromats performing much like a classical f/15 achromat. The Fringe Killer delivers improved resolution, contrast, image brightness, with a very aesthetically pleasing view.




Digital Imagers (CCD, DigiCam, and Webcam) will find the Fringe Killer Telescope Filter by Baader to be the ultimate mate for their achromatic refractor. The high transmission and fringe reduction work great for planetary or deep sky imaging. Baader included their renowned UV/IR Cut coatings as part of the Fringe Killer formula. These coatings maintain very high transmission, with well placed sharp cutoffs in the IR and UV. The high quality of Baader Planetarium filters also permits stacking, with no image degradation.
