The O-III benefits from the precision fine optically polished flat substrate, and advanced DWDM plasma-assisted coatings. As a result, the Baader O-III will not degrade image sharpness or impart double images. Baader O-III filters can take high magnifications, and stars retain their pinpoint sharpness, even if the filter is used far ahead of the image plane. Baader filters are truly designed to be stacked and combined due to the high optical quality and highly efficient anti- reflection multi-coatings. Each substrate is fine-optically polished plane parallel to deliver a smooth and accurate 1/4 wavefront over the entire surface.
Baader’s Anti- reflective coating technology, ¼ Wave fineoptical polish, Ionbeam hardened coatings and fully sealed coating edges for long life. Baader's special filter cell design offers unique features that enhance their reliability and usability. The ultra-thin filter cell results in the maximum possible clear aperture in order to minimize vignetting. The special threading has been designed to fit a wide variety of eyepieces and accessories. The front 'crown' of the filter incorporates milled notches which make handling and threading the filter a more secure operation in the dark.
