Each of the red, green, and blue images is a combination of 3 images, each of 120 seconds The images were taken with a Pictor 1616 with a Pictor 616 filter wheel attached to an Meade 10" F/6.3 telescope. A Pictor 201XT was attached to an ETX for guiding. Meade Red, Green, and Blue filters were used. No attempt was made to correct for different sensitivites in the three bands.
Each of the images was corrected with a dark frame and a flat field. The same flat field was used for each of the color channels. This image is binned, an unbinned version is available.
