Clouds of Dust and H-Alpha around Sh2-120 and NGC 7031 in Cygnus
Sh2-120 and NGC 7031
There are indeed still a few regions in the constellation Cygnus that are rarely photographed. The area around NGC 7031, Sh2-121, and Sh2-132 is one such blind spot, despite the fact that it contains a multitude of spectacularly shaped dark nebulae (LDNs), H-alpha clouds, reflection nebulae, star clusters, a small planetary nebula, and even a special variable star (V 1331 Cyg).
