NGC 6604 (also Collinder 373 and OCL 56) is a magnitude +6.5 open star cluster located 5,500 light-years away, about two degrees north of the Eagle Nebula, in the constellation Serpens.

The cluster was discovered by German-British astronomer William Herschel using a 47.5 cm (18.7 inch) f/13 speculum reflecting telescope at Datchet, Berkshire, on the 15th July 1784.

Right Ascension 18h 18m 03.0s, Declination -12° 13' 00"

A Cluster Within a Cluster

eso1218a.jpg

The star cluster NGC 6604 is shown in this new image taken by the Wide Field Imager attached to the MPG/ESO 2.2-metre telescope at the La Silla Observatory in Chile. It is often overlooked in favour of its more prominent neighbour, the Eagle Nebula (also known as Messier 16), that lies a mere wingspan away. But the framing of this picture, which places the star cluster in a landscape of surrounding gas and dust clouds, shows what a beautiful object NGC 6604 is in its own right.
NGC 6604 is the bright grouping towards to the upper left of the image. It is a young star cluster that is the densest part of a more widely scattered association containing about one hundred brilliant blue-white stars. The picture also shows the cluster's associated nebula - a cloud of glowing hydrogen gas that is called Sh2-54 - as well as dust clouds.
