Optolong L-Pro RDF diffraction-limited optical systems are multi-coatedDescription The L Pro (L Professional) filter is the best light pollution filter with multi bandpass filter which offers better color balance by maximizing the transmission band 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
