This open star cluster is known as Messier 67, aka. the King Cobra Cluster aka the Golden Eye and is located in the Cancer Constellation, with age estimates ranging from 3.2 and 5 billion years. This cluster is one of the oldest clusters known. It is the closest of any of the older open star clusters.
Charles Messier independently discovered the cluster and added it to his catalogue on April 6, 1780. He was able to resolve it into individual stars and described it as a “cluster of small stars with nebulosity, below the southern claw of
Cancer ."William Herschel observed M67 several times. After seeing it in his 20-foot telescope in 1784, he described it as a “most beautiful cluster of stars; not less than 200 in view.”
The image of M67 was conducted in a single night but more integration is possible, weather permitting [haha].
Not sure why the nicknames, TBH. I don't see a cobra or an eye.
