I took this from my backyard in 2007. It was a faint bugger that seemingly took forever to capture in tricolor emission line. I did this at full resolution instead of binning 2x2 (which would have sped things up considerably). I just wanted it with as much detail as my system could supply
After 22 hours of exposure over a month roughly I decided to stop. I may shoot this one again from the ranch with the much better skies/seeing...
