Narrowband imaging is classed as using filters that allow a narrow band width through them. Traditionally these filters are, Ha ( Hydrogen Alpha ) Wavelength 656 nm 0111 (Oxygen 111 ) Wavelength 501 nm & S11 ( Sulphur 11 ) Wavelength 672nm.
My black and white images are imaged in Hydrogen Alpha using a Baader Ha filter.
