Sharpless 119 is a large patch of emission nebulosity in Cygnus, about 3 degrees east of the North American Nebula, located around the bright 5th-magnitude star 68 Cygni (near the image center). S. Sharpless, in his famous "Catalogue of H II Regions", published in 1959, indeed describes it as type 3, "bright". Interestingly, there are several dark lanes and dark globules superimposed on the southern part of the nebula. The area is part of the Milky Way and well populated by numerous stars.

There is a planetary nebula present called We 2-245 and is the small blob to the left of the bright star near the centre. It is one of 6 planetary nebulae that were discovered in 1977 by the astronomer Ronald Weinberger. (thanks to Sakib for pointing this out)
