Lynds Bright Nebula 239 is one of the brighter in the list. Located above Sadr in Cygnus, this image is centered on LBN 239. The brighter nebula at the top left is IC 1318 (LBN 251). The nebula at the top right is LBN 243. The open cluster at the right is IC 1311.
Note that I also caught Asteroid 4558 Janesick. This is the small line found in the bottom right corner.
Luminance – 12x600s – 120 minutes – binned 1x1
