Located 1,600 [[light year]]s away, the nebula is around 50-56 light years across.<ref name=apod/><ref name=seds/> The brightness of the nebula varies drastically across the nebula, with the brightest regions having an [[star magnitude|apparent magnitude]] of +4.5 while the dimmest areas have an apparent magnitude of +12.<ref name=freestarcharts/> The nebula overall however is generally very faint and has a low surface brightness. The brightest areas of the nebula that resembles [[Central America]] and [[Mexico]] is composed [[dust]], hot [[gas]] and [[star]]s, a region known as the Cygnus Wall.

The nebula is likely associated with three nearby [[open star cluster]]s. NGC 6989, discovered by [[William Herschel]] in 1790, is located in the North-West region of the nebula.<ref name=seds/> Near NGC 6989 is NGC 6996, discovered by [[John Herschel]] in 1833. NGC 6997, discovered by [[William Herschel]] in 1786, is situated on the western side of the nebula.
