Here is the Claw Nebula in the Hubble palette (SHO). Hope I didn't go overboard with the colors. It was a little tricky to process since some of the interesting features are a bit faint.

I have also done a bi-color version here, which has a more "natural" look. Which version do you prefer?

I feel like I might like a bit of green, but some don't so uploading a version (B) with the green removed. Which camp are you in? :)
