Description:
The discovery of IC 4665 is attributed to the Swiss astronomer Philippe Loys de Chéseaux, who observed it and included it in his catalog of "nebulous" objects published in 1746. Curiously, it was not included in the Messier Catalogue, although it had already been discovered over a quarter of a century before Charles Messier compiled it. Likewise, it was not reported by William Herschel, probably because of its large size. It was not until the publication of the second Index Catalogue, a corollary to the New General Catalogue, that this object received a catalogue number. For this reason, I wanted to nickname this beautiful cluster "The Neglected Star Cluster".
