This object is very strong in H-Alpha so I may need to go back and get
more data and maybe some h-alpha. This was brutal to bring out the
detail with so little data. Don't look too closely!
From Walter Koprolin: " 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).
It shows up quite easily in well-exposed wide-angle photographs of the
region as large red patch of emission nebulosity. 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. "
