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.
