Another shot from OSP. I used H-alpha for red, but included G and B channels. There is some L exposure also, but luminance comes mostly from H-alpha. I'm still experimenting with ways to combine narrow- and broadband images.

Thanks! The exposures are:
H-alpha: 5 x 15min
L: 10 x 4min
B/G: 8 x 4min each
So about 3 hours total. However, the luminance channel is a fairly small part of the final image, unlike a typical LRGB image.

Great shot - how much time did you put on it?
