Sh2-176 is a planetary nebula in Cassiopeia
Sh2-176 (LBN 597, PK 120-05.1, PN G120.2-05.3) is a planetary nebula in the constellation Cassiopeia . It is a telescope object, 6 inches or larger, and it is highest in the evening sky in November.
Planetary nebula: a shell of gas thrown off by a dying Sun-like star and lit by the hot core left behind, which becomes a white dwarf. The name comes from their small, round, planet-like look in early telescopes.
Sh2-176 is Sh2-176 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; Sh2-176 is faint (class 1 of 3). It is also listed as LBN 597.
