Sh2-112, Sh2-115, Sh2-116, and Weinberger 1-10 (We1-10; PK 086+05.1; PN G086.1+5.4) are faint emission nebulae located in the constellation Cygnus , near Deneb. Sh2-112 and Sh2-115 are classical H II regions , consisting of extensive clouds of hydrogen gas ionized by the intense ultraviolet radiation emitted by young, massive O- and B-type stars. Their structures include ionized gas, interstellar…
