Sh2-146 is an emission nebula (H II region) in Cepheus
Sh2-146 (LBN 514) is an emission nebula (H II region) in the constellation Cepheus . It is a telescope object, 6 inches or larger, and it is highest in the evening sky in October.
Nebula: a cloud of gas and dust. Emission nebulae glow on their own, lit by ultraviolet light from hot young stars; reflection nebulae shine by starlight scattered from dust; dark nebulae block the light behind them.
Sh2-146 is Sh2-146 in the Sharpless catalog
Stewart Sharpless listed it in his catalog of H II regions (1959), drawn from the red and blue prints of the Palomar Sky Survey. He rated each region's brightness on a scale of 1 to 3; Sh2-146 is medium (class 2 of 3). It is also listed as LBN 514.
