Omega Cygni

Omega Cygni was an inhabited planet. This was the homeworld of the Omega Cygni natives.

In the mid-23rd century, Harry Mudd visited Omega Cygni, where he turned a handsome profit selling the natives their own oceans. 

In 2293, the location of Omega Cygni in the Milky Way Galaxy was labeled in a star chart that was in James T. Kirk's quarters aboard the USS Enterprise (NCC-1701-A). (, okudagram)
