The Ha [+NII] signal is overwelming in this area of the sky, but there is also prominent SII and some (less) OIII, so I mapped SII (and some OIII) to blue, Ha to red, and created a synthetic green channel to achieve this bi-color image. The effect is to show Ha in red contrasted with the weaker SII signal.
