IC4665 aka "The Summer Beehive" in Ophiuchus - RGB


IC4665 - The "Summer Beehive" Open Cluster in Ophiuchus


Discovered by De Chéseaux 1745-1746.

IC 4665 is one of the brighter Milky Way clusters missing not only in the Messier Catalog, but also in the NGC, because it is so loose and coarse. Nevertheless, this cluster in Ophiuchus is a good object for binoculars or wide-field telescopes.
