Baader SII CCD Narrowband-Filter (8nm) 31.7mm is used to deliver the highest deep sky images in H-Alpha, H-Beta, Oxygen III and Sulfur-III with the shortest exposures possible. These filters are designed for CCD astrophotography and an essential accessory for lunar and planetary observations. The Baader Narrowband SII will block all unwanted sodium light pollution and longer wavelengths. Baader 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. 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. The front 'crown' of the filter incorporates milled notches which make handling and threading the filter a more secure operation in the dark.
