This interesting open cluster can be found in
northern Puppis, about 13 degrees west of Sirius and nearly 20 degrees
south of Procyon.
It is estimated that M46 consists of nearly 500 stars that are about 300
miliion years old. Apparently within the cluster, but most likely in
the foreground, can be seen NGC2438, a small mag 10.1 planetary nebula.
