 This small but highly detailed emission nebula is part of a quartet of Sharpless nebulosities within a few degrees of sky inside the pentagon of Auriga. Central to this image is the main section of nebulosity which is surrounded by a dimly glowing cloud of hydrogen. On the upper left, the glow represents part of Sharpless 232, a huge object spanning several degrees. Near the bottom center, the "detached" piece of nebulosity was a bonus - a faint PK planetary nearly half an arcminute in size.

This is the start of a really deep set of exposures on this region, this red luminance frame will be the basis for a more complete color image in the month to come.
