I posted a picture of M8 a couple weeks ago that was pretty impressive, compared to what I had done before. Here is a picture 100x better. Since I signed up for the Astronomy course at Chapel Hill UNC, I can access their awesome 15" (16?) telescopes on a Chilean mountain with no light pollution. This is 15 photos of 40 seconds each, (5 each using a red, green, and blue filter), plus darks, flats and bias (astrophotography exposures necessary when using expensive ccds) stacked together in Deep Sky Stacker and edited in iPhoto. So that's a total of 10 minutes for one final picture.
