Data for this image was taken during March, 2011, using a remotely controlled o.37m (14.5″) Ritchey-Cretien telescope in Rodeo, New Mexico, owned by LightBuckets. Total exposures were 90 minutes (13 frames) for luminance and 30 minutes (6 frames each) for red, green, and blue chrominance. Software used was CCDStack 2 for calibrating and PixInsight for the remainder of the processing.
