The picture was taken with a fully modified Canon Rebel camera (thus one shot color (OSC)) on a TEC 140 telescope from the Alpenglow-Torrey House Observatory in the dark sky community of Torrey, Utah (Bortle 2-3). 12 two-minute sub frames stacked in Deep Sky Stacker = 24 minute photo. Processed in Photoshop (CS5). Unguided, no calibration frames.
