Description

I had planned to do this in a Hubble Palette and just did not like the colors so I combined the HA, OIII and SII to bring out all of the nebulosity and then built in RGB by combining the nebulosity with the Red Channel and then adding back in the RGB stars. An interesting workflow to be sure!

Uploaded a new version that got rid of some blue gradient on the left side of the image

Uploaded an SHO version, not happy with the salmon stars so will address those as well.
