Description

Since some call this target the Butterfly Nebula, I thought it is a good time to try out Eric Coles' new tone mapping technique. The result is definitely interesting. What do you think?

PS. Does anyone else notice a tiny pinkish planetary nebula just to the left of the butterfly's head (half way between the head and the edge of the image). I thought it is a star at first.

Description: I was a little conservative on my initial version, possibly due to being new to the wider color palette. This revision should be more in line with my other images.
