Introduction | Map | My Own Photos | Own Observations | References
On this page I collect my observations of the open star cluster M 47 (NGC 2422 = NGC 2478) 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 47 and M 46, which are located so close to each other in the sky that, at low magnifications, they can even be observed together. This is possible with the Vespera, but not with the eVscope (2).
When I take a mosaic of M 46 and M 47 with the Vespera, the open star clusters NGC 2423 and NGC 2425 (both Puppis) also appear in the photo!
