Cheers boys thanks for checking her out
Steve, this image was composed with a relatively small amount of RGB enhanced with Ha and OIII, it is therefore probably best described as more of a
simulation if you like, of an LRGB and processed to closely match what an LRGB should look like....so, you may well be right but hopefully at least the
essence of the image is reasonably accurate and remember these nebs are indeed meant to be magenta (mostly red Ha + some blue Hb) in most cases...unless plenty of dust is in the road of course then they look
deeper red/orange...that's the theory anyway
