William Herschel discovered the cluster in 1784, the nebula in 1785.

The Chrismas Tree Cluster and the Cone Nebula were both discovered by William Herschel. He found the cluster on January 18, 1784 and cataloged it as H VIII.5, and the nebula on December 26, 1785, and assigned it the number H V.27. The nebula belongs to a much larger complex, which is currently an active star forming region.
