NGC2467 is an open cluster and surrounding nebulosity in the Milky Way of Puppis east neighbor of Canis Major. The nebula can be found out about 9.5 degrees just east from delta CMa at the waist of great dog. You can appreciate only sparse cluster with telescope, reddish nebula comes to sight only on the long exposed photographs. The nebula shows us a round and bright part in west region with a diameter of about 16 arc minutes, but actually the nebula has stretched very dimmed filaments eastward. In case of including this faint part, the nebula has a span of over 30 arc minutes.
