I managed to get some OIII and SII data on the Elephant Trunk, although I need quite a bit more of both to bring up the SNR and do a proper rejection... you can see really poor star shapes and some noise. But I was getting impatient and wanted to play around with the data. :)

A bit more saturation and contrast for Astrobin....


Reduced greens and a bit of the magenta halos, adjusted contrast and general gold/blue tones... just a little tweak.
