This is the RGB + Luminance. I have to say this has been one of my toughest projects to process. If conditions allow I will be adding HA to this soon. Total Exposure time 10 hours and 40 minutes. Incidentally I am using CCD Stack for the very first time and I am impressed, I might have to go back and reprocess everything now:) I hope you like the result.
