I shot this sequence on 08/30/2011 from my backyard Observatory. I used a Celestron C9.25 with Celestron F:6.3 Focal Reducer. The camera used was a Canon 500D. The whole rig was autoguided by an Orion Short Tube 80 Refractor and Starshoot Autoguider. The sequence starts at 12:30am EDT, and ends at 3:30am EDT. The exposures were 2 minutes at ISO 1600, and are approx 10 minutes apart. The sequence was compiled using Imageready, Flash, and Fireworks.
