                                 This picture is a collaboration between Bernard Miller from Phoenix, AZ

                                 and Arie Nagel, Eindhoven, Netherlands. Arie took the luminance date on his

                                 300mm Newtonian and combined it with the RGB from Bernard's TEC-140. Both

                                 used the SBIG ST8300M camera. The image processing was done by Arie and Bernard.
