This image was taken with our Officina Stellare RiLA 600mm f/5.0 telescope using an FLI ML16200 CCD camera cooled to -25C. Luminance detail was added to exposures taken through red, green and blue filters to create this full color image. Imaged and processed in Samphran, Thailand by the SC Observatory team: Mike Selby, Stefan Schmidt and Andy Chatman.
