This is the result of 8 hrs of LRGB integration from the El Sauce Observatory in Chile. Initially it seems to be easy to process but once I got down to it, it was a challenge to bring out the whispy antennae and to bring out the colour in them without overexposing everything else. I didn't want the background clipped (too black) either.
