WebThe strongest hydrogen emission line, the H-alpha line at 656.3 nm, gives H II regions their characteristic red colour. (This emission line comes from excited un-ionized hydrogen.) H-beta is also emitted, but at approximately 1/3 of the intensity of H-alpha. WebJul 17, 2016 · As for accentuating your Hb and OIII emissions, I would suggest 1) ample IT, and 2) in post processing just work on the GB channels separately (i.e. suppress the R to nil) after stacking.
