SV80ST Refractor @ f/4.5 Riccardi .75x Reducer Starlight Trius SX694  Atik EFW2/OAG  Astrodon RGB/Ha,OIII Losmandy G11-Gemini 2

RGB=20x15min each Ha=8x20min OIII=9x20min
Total = 20hrs 40min 

This was a very difficult image to process. My goal was to retain the correct RGB color palette while enhancing with Ha and OIII in the red and blue channels.
