The Optolong S-II (Sulfur-III) extra narrowband filter is designed to improve the visibility of various deep sky objects. It does this by:
Selectively reducing the transmission of wavelengths of light pollutants, specifically those produced by artificial lighting (including mercury vapor lamps, both high & low pressure sodium vapor lights, and the unwanted natural light caused by neutral oxygen emission in our atmosphere (i.e. skyglow)).
Allowing 6.5nm bandwidth of light centered on a wavelength of 672nm to pass through, which corresponds to SII emission lines.
