Sharpless 73 in Hercules was initially thought to be an HII emission nebula (hence it's inclusion in Sharpless' catalogue). It is now known to be a molecular cloud.

Sharpless 73 was imaged between 29 April and 22 May 2020 from an imaging rig in Spain that is privately owned and operated by Barry Wilson and me.
