BAADER CONTRAST-BOOSTER 48MM/ 2''
Much more than a simple minus-violet filter. Based on the popular Baader Moon&Skyglow filter, the Baader Contrast-Booster takes contrast enhancement and skyglow reduction to the maximum level possible from a filter. Not only does this filter deliver a significant enhancement of planetary and lunar contrasts, but it is designed to also totally eliminate the damaging blue defocused haze present in achromatic refractors. Gone are the annoying blue halo and obscuring haze that surround and smear resolution and contrast. Subtle contrasts and colors are boosted, while displaying the full resolution your scope is capable of.
Combined with the Baader UV-IR-Cut Filter, the Contrast-Booster makes the ideal filter set for digital imaging.
