On this page I collect my observations of the open star cluster M 46 and the nebula NGC 2438 in the constellation Puppis.
The constellation Puppis is also one of the constellation that were unknown to me, particularly, because it belongs to the southern sky. It contains the two open star clusters M 46 and M 47, which are located so close to each other in the sky that, at low magnifications, they can even be observed together. M 46 is visually included in the planetary nebula NGC 2438, which I was not able to find, though.
Size: 20' x 15' (Stoyan)
