M46/M47 Region in Puppis

The full-frame overview of the M46/M47 region
in the constellation Puppis gives a nice sense
of scale and context to the objects we normally
see individually in our telescopes. Embedded
in the cluster M46 is an even smaller planetary
nebula NGC2438 which appears as a little red
dot in this widefield photo.
Actually, it's not really physically embedded
in the cluster,
but just appears so because it happens to be
lying in the same direction as M46 as we view it.
