Discussing with a friend about what M 24 is, it is a peculiar object of the Messier catalog. It is not an open cluster, it is a galactic condensation. When I observe this with my traveler scope, with a large field of vision I see this great condensation seen with the naked eye. With the scope surrounded by dark nebulae I see a small group or brighter fluff, So far I thought that is M 24, since the size corresponds to the vast majority of catalogs in size refers 6 arcmin.
This item is also included in the new general catalog with the number 6603. Actually if M 24 is a galactic condensation and it is really what I see around 2 ° in the sky, because no catalog corresponds to that measure.
I would like someone to clarify the error and explain why this object is so peculiar in the catalog.
