The Baader O-III perfectly isolates the two doubly ionized oxygen lines through a very sharp and narrow bandpass, the narrowest of any O-III filter, while the Baader SII will block all unwanted sodium light pollution and longer wavelengths. Baader's H-Alpha filters ultra narrow bandwidth with extremely high transmission rates enables high-contrast deep sky images. The high optical quality of the Baader narrowband filters guarantees no loss in sharpness or contrast. Each substrate is fine-optically polished plane parallel to deliver a smooth and accurate 1/4 wavefront over the entire surface. This special custom polishing operation sets Baader filters apart from the standard commercially precision polished filter substrates used by most other filter manufacturers. Baader Planetarium filters are truly designed to be stacked and combined due to the high optical quality and highly efficient anti-reflection multi-coatings. Premium quality coating is applied that offers optimum light transmission.
