M24 Small Sagittarius Star Cloud
M24 Small Sagittarius Star Cloud
This is the Sagittarius Star Cloud M24 that sits in the constellation Sagittarius. It is one of the more dense star clouds and visible with binoculars and even the naked eye on nice nights. The dark black dust is not a hole in the star cloud, but rather blocking it’s view because it’s so dense. NGC 6603 is that small little open star cluster.
