The Eagle Nebula, also known as Messier 16, lies in the constellation Serpens. This image was made by the 0.8-meter Telescope at McDonald Observatory, with the Prime Focus Corrector instrument. To obtain a color image, three exposures were added together, one made with a red filter, one with a green filter, and one with a blue filter.
