Astronomy Pics: Rosetta Nebula

My husband has been working on his newest endeavor: astrophotography.  He has quite a nice setup to play with consisting of a RC 12.5" telescope, with an Apogee U16M camera (16 megapixel, full frame sensor), and a Paramount ME for tracking.  The weather has been really clear lately so we've finally had a good chance to test it out.  He just got his first 20 minute exposure with decent tracking.  It's part of the Rosetta Nebula, shot with a Hydrogen Alpha filter. No retouching has been done yet, so it's exciting to see this!
