Ever since I started astrophotography, M20 has been at the top of my list. Unfortunately, it doesn't rise high enough from my usual imaging location. I was traveling this past weekend and so I tried using the one-shot color on it. Conditions were terrible - clouds, haze, even some fogginess - so I only managed to get 20 frames in total. Still: despite the noisiness (and inability to use the monochrome camera or the Newt), I'm thrilled that I was finally able to shoot it. Plenty of room for improvement next year, but I finally got it.
