This object provides
a challenge in composition. The main bright portion is not central
to the object, and by offsetting the cluster to the lower right,
the field I wanted was obtained, with the large blue loop on
the right well framed. This was an experiment to see what could
be captured in color in only 15 minutes at ASA1600. The camera
did well, and the noise was low for a non cooled camera.
The very loose splashy open cluster in which the nebula surrounds
is NGC1977, a 20 arcminute in size object around 5th magnitude.
The blue reflection nebulosity is NGC1973 and NGC1977. They surround
the cluster and is more than half a degree across. My field is
1 degree diagonally, and they must be referring to the brightest
parts for size. The dark man shaped bay inside the nebula is
the Running Man. It is more plum colored than the blue of the
