CHROMA TECHNOLOGY SII FILTER Bandpass:5nm the telecentric design does notChroma narrowband filters are the highest performing filters on the market today. They are available with a range of bandpasses and sizes to suit any configuration where the finest image quality is of paramount importance. The Chroma SII filter isolates 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
