Omega Cygni was an inhabited planet in the Alpha Quadrant. This was the homeworld for the Omega Cygni natives, an intelligent species. Its location in the Milky Way Galaxy was depicted on a Federation star chart in 2293. (Star Trek VI: The Undiscovered Country, production art)
Omega Cygni was misspelled "Omega Cyngi" on "The Explored Galaxy" star chart. "The Explored Galaxy" was a map of charted space in the Alpha Quadrant. Omega Cygni was located between the Tholian Assembly and Romulus. Both locations were identified in DS9: "The Search, Part II", "Call to Arms" as being located in this quadrant. The chart, first seen chronologically in Star Trek VI: The Undiscovered Country, was also seen in several Star Trek: The Next Generation and Star Trek: Deep Space Nine episodes set in the 24th century, from the year 2364 to 2370. These were TNG: "Conspiracy", "The Measure Of A Man", "The Emissary", "The Mind's Eye", "The Game", and DS9: "In the Hands of the Prophets", "Cardassians".
According to the Alan Dean Foster novelization of TAS: "The Time Trap" in Star Trek Log 4 and Star Trek: SCE, Magen was a Cygnian from Omega Cygni. In the novelization of "Mudd's Passion" in Star Trek Log 3, the name "Omega VII" was used of this planet.
