NGC 281, commonly known as the Pacman Nebula for its resemblance to the video game icon, is a HII region located in the constellation of Cassiopeia at a distance of approximately 9,600 light years. The visible structure of the nebula spans a distance of approximately 60 light years. Like in the Eagle Nebula, the Pacman contains several pillars and dark globules. These areas are active stellar nurseries where new stars are being created. Dr. Robert Gendler published an very informative article describing, in some detail, the Pacman Nebula. It may be viewed here. The image above was compiled from narrow band filtered exposures to create a mapped color depiction of the Nebula. The standard Hubble pallet of SII to red, Ha to green, and OIII to blue was utilized for the image. 1http://en.wikipedia.org/wiki/NGC_281
