M16-2
M 16, the Eagle Nebula with Chile Two telescope of the Slooh network and processing with Pixinsight.The Eagle Nebula (also known as Messier 16 or NGC 6611) is a large H II region in the constellation Serpent's Tail. It is formed by a young open cluster of stars associated with an emission nebula composed of ionized hydrogen, cataloged as IC 4703.
Its distance has always been relatively uncertain, but there is a tendency to accept a value of about 7000 light years from Earth, thus placing it in the middle zone of the Sagittarius Arm; it contains some extremely well-known formations, such as the Pillars of Creation, the long columns of dark gas originating from the action of the stellar wind of the components of the central cluster and which are also responsible for the proper name of the nebula itself, due to their shape. In them there are some young stellar objects, which testify that the processes of star formation are still underway, although it is not clear whether these are favored or opposed by the action of the stellar wind of nearby stars, nor is it clear if the wind actually affects these phenomena in some way. The cluster is composed of a large number of very hot and bright blue supergiants; their typical age is just 2-3 million years, that is, less than one thousandth of the age of our Sun; The brightest star in the cluster is magnitude 8.24, clearly visible even with binoculars.
The nebula has been known since the eighteenth century and is one of the best known objects among those of the Messier Catalog; It reveals itself easily in photographs and is therefore a good subject for fans of amateur astrophotography.
