This four-panel mosaic of an area in Cepheus is part of a much larger work I completed sometime later. I wanted to isolate it because it contains five Sharpless objects in a compelling field that the astrophotography community neglects in favor of much more famous objects (out of this frame) around it.
The field contains Sh2-134, 135, 138, 139, and 144 as well as a runaway star with bow shock. I've documented much more detail on these objects in the full twelve-panel mosaic.
