This image was obtained by Tim Hunter and James McGaha from their Grasslands Observatory near Tucson, Arizona. They used a 24.5-inch reflecting telescope and Apogee AP-7 CCD camera. Notice also the small background galaxy IC 1296.
William McLaughlin took this colorful CCD image of the Ring Nebula, Messier 57. This is a true color image. William took it at his ARGO Observatory with a RC Optical Systems 12.5-inch RC telescope at f/9, mounted on an Astro-Physics 1200GTO mount. It is a composite of four images with an SBIG ST10E CCD camera, exposed 5 minutes each, and 8 exposures for each color, with a FLI "Dream Machine", 1 minute each for red and blue, and 45 seconds for green. The image was taken in May, 2001.
