NGC 281 (IC11) in the constellation Cassiopeia is dense cloud of protons floating in space, reflecting a little bit of light from nearby stars.  It also bears a resemblance to the video game character Pac Man — giving it the name “The Pac Man Nebula”.

Taken over two nights (10/18-10/19) with 10 hours of data in hydrogen-alpha light and 6 hours of data through clear, red, green, and blue filters.
