The Baader Semi APO filter has unique properties that result from the combination of the Fringe Killer's blue wavelength attenuation (attenuation - not total elimination), plus the selective Neodymium RGB passbands, resulting in a significant contrast enhancement of Martian features. Unlike other manufacturer's filters, the image retains its natural colouration and brightness, and the optically polished surfaces maintain every bit of the image sharpness.

The high quality of Baader Planetarium filters permits their use well ahead of the focal plane with no image degradation (ie, for cameras or binoviewers). The inclusion of Baader's renowned UV/IR Cut coatings on the Semi-APO eliminates UV and IR wavelengths to make it ideal for high-resolution imaging with Webcams, DSLR, and CCD cameras (see the UV/IR Cut filters below, for more detail on these coatings). The high transmission and fringe reduction work great for both planetary and deep sky imaging.
