Messier 46 is a rich star cluster in the constellation Puppis.
There are an estimated 500 stars in the cluster, and it is thought to
be some 300 million years old. As a special and famous feature which
is also obvious in the above image, a planetary nebula (NGC 2438)
appears within the apparent borders of M46.
This nebula is most probably not a true member but is superimposed,
or perhaps a passing guest.
To the north of NGC 2438 another small and faint planetary nebula
(M 1-18) is visible in the above image.
