M50 (NGC2323) is the only Messier object in this constellation, an open cluster with a size of about 16 arc minutes.
You'll find out the cluster near the boundary to Canis Major. Sirius (alpha CMa) is a good mark to search that, about 9 degrees NE of the brightest star in the sky.
The cluster contains approximately 80 fine stars, and a nebula-like view will be appreciated through binoculars.
Distance is estimated about 2600 light years.
