NGC 2392 Eskimo Nebula
| Description |
NGC 2392 Eskimo Nebula is small but bright object. It is difficult to process and acquire. You would need a long focus large aperture instrument. The Eskimo Nebula (NGC 2392), also known as the Clown Face Nebula, Lion Nebula, or Caldwell 39, is a bipolar double-shell planetary nebula (PN). It was discovered by astronomer William Herschel in 1787. The formation resembles a person’s head surrounded by a parka hood. It is surrounded by gas that composed the outer layers of a Sun-like star. The visible inner filaments are ejected by a strong wind of particles from the central star. The outer disk contains unusual, light-year-long filaments. NGC 2392 lies about 6500 light-years away, and is visible with a small telescope in the constellation of Gemini. At the center of NGC 2392, there is an O-type star (designated HD 59088[7]) with a spectral type of O(H)6f.
