M13 from dark sky site in Southern California. Shot with DSI-Pro on 10-inch Meade LX200GPS at f/4; 60-sec subs guided with DSI-c on 80mm Williams Optics refractor at 1000 mm focal length. Total integration times were 60:15:15:15 minutes for each of LRGB. Image capture with MaxDSLR, stacking and baseline processing in CCDStack and final editing in Photoshop CS2. A bit more noise than I'd like, but there it is...
