A few years ago, a composition by Michael Stecker caught my eye and I have always wanted to visit this composition with a DSLR.
The area in this composition is on the Cepheus and Cygnus border and has been catalogued as Globular Filament 7.
The dark "x shaped" nebula in the center of the frame is the area identified as Globular Filament 7. I am not sure as to the exact area that is identified as the filament.
My reference for the object ID is from Jerry Lodriguss' page where he notes that the object was
catalogued as Globular Filament 7 by Schneider & Elmegreen in 1979 (ApJS 41, 87.)
Seeing this dark nebula area visually is a good indicator of sky conditions where higher contrast marks excellent transparency.
