Shrimp Nebula is a planetary nebula in Cassiopeia
Shrimp Nebula (Sh2-188, Firefox Nebula, LBN 633, PK 128-04.1, PN G128.0-04.1) 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.
Shrimp Nebula is Sh2-188 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; Sh2-188 is medium (class 2 of 3). It is also listed as LBN 633.
