Thank you for supporting this wiki project
NGC 2438 is a planetary nebula in the constellation of Puppis, the stern of Argo Navis. Visually displayed in the confines of the open cluster M46, but in reality is closer to us, about 2900 years away light. It is very difficult to identify because it is essential to enjoy a very dark night. It is fascinating to observe both, a nebular filter can help a lot to its observation.

The nebula's central star is magnitude 17.5 (which is very dim at this picture) and displays a continuous spectrum. Near it is seen a bright star, probably a member of the cluster M46 and therefore almost twice as far. Many other of the visual field stars also belong to the cluster.

NGC 2438 was discovered by William Herschel in 1786. The picture was taken on 2010-10-13 using a 6 inch refractor telescope.
