This narrowband image will be one of a series of the Veil Nebula. The Eastern Veil is already done (see my photos) and I'm working on the Western Veil as I write this. The channels are R=H-alpha, G=SII, B=OIII. However, the hues is shifted a bit to make it more pleasing. At a glance it appears that H-a and SII are very similar, producing a lot of yellow/orange areas. But on closer examination you can see a lot separate colors.
