That's awesome Martin! I really like the central part were the dark nebulosity edge is and you can see the lighter background blending into the pinkish then blue sky. It has a real depth to it. The only thing I don't like about narrow band pictures in general is that the stars almost always have darker halos around the brighter core. It's ok when the stars are on a darker background but they stick out when showing on top of a lighter background. It looks like they're pasted on top of another layer. Is this caused by stacking the different channels? Having said that I have never tried NB and I assume it must be very trying to get the data in the first place and process it. Never the less it's such a great picture. Well done.
