Description:
Messier 46 (also
known as M 46 or NGC 2437) is an open cluster in the constellation of Puppis. It
was discovered by Charles Messier in 1771. Dreyer described it as "very
bright, very rich, very large." M46 is about 5,500 light-years away with an
estimated age on the order of several 100 million years. The
planetary nebula NGC 2438 appears to lie within the cluster near its northern
edge (the faint smudge at the top center of the image), but it is most likely
unrelated since it does not share the cluster's radial velocity. (Wikipedia) Deepskystacker
