Image of the Ring Nebula (Messier 57) taken from the WCU observatory with the ST-8XME Camera provided with Tech Fee funds. The ring is a shell of ionized gas that was expelled from a red giant star and is expanding, leaving a white dwarf at the center. The image is a composite of three 60-second exposures in B, V, and R Johnson filters, and has been low-pass filtered. The image was acquired by Physics majors Nicolas Legall and Trevor Davis, and, and later processed by Brittany Johnstone and Brett Sheriff. The project was supervised by Dr. Thornton of the Department of Physics.
