| Description | This
is a very nice open cluster for
binoculars and small
telescopes. This image
only shows a section of the
northern part. M46 is best
known for the superimposed
planetary nebula NGC2438 which
appears at the centre of the
image. NGC 2438 is not
part of the cluster and is in
fact some 700 parsecs closer.
