This color image is based on data coming from several photographic plates taken between 1989 and 1993 through the Palomar Observatory's 48-inch (1,2-meter) Samuel Oschin Telescope as a part of the second National Geographic Palomar Observatory Sky Survey (POSS II). The photographs were recorded on two type of glass photographic plates - one sensitive to red light and the other to blue and later they were digitized.
