Hb emission is about a third the intensity of Ha. It requires more energy to kick the electrons up another shell. You can simulate the Ha+Hb by adding red and blue in appropriate proportions... to give the magenta that we all know and love
Sorry for converting your deep sky image thread to a physics discussion, Paul
