OBJECT DESCRIPTION AND IMAGE SESSION

NGC 6437 is located one degree to the south west from Messier 7. This remarkable star field from our Milky was catalogued by British astronomer John Herschel in 1837. (*)

NGC 6437 is frequently seen as non existent object, an open cluster or asterism. Clearly not an asterism nor an open cluster, but more likely to be a stellar cloud. Because its stellar characteristics Herschel considered it in his catalogue.  (**) 

 

Stellar clouds are quite suitable objects for urban skies astrophotography. This type of clouds are so bright that even moderate city light do no disturb the spectacular nature.
