Chroma Technology 3nm/5nm/8nm SII Filters (27009/27010/27011) imaging computer Brass Motor drive 1SII filters isolate the spectral emission of singly ionized sulfur atoms, also common in nebulae. Emission is at two lines occurring as a doublet, at 671. 6 and 673. 1 nm. This filter also separates sulfur emission from H alpha emission (656. 3nm).
