NGC2392 is a tiny planetary nebula about 4 degrees ESE of delta Gem that marks the body of Castor, the elder brother of twins.
The nebula has an apparent diameter of less than 1 arc minute, and it might be difficult to distinguish the nebula from the normal stars unless 4-inch telescopes or larger.
You need a magnifying power over 100 to enjoy the detailed structure.
The planetary nebula has a bright central region and the surrounding dimmed ring-structure.
This shape gave NGC2392 a unique nickname of "Eskimo Nebula" because the shape associates a face of Eskimo with his head hooded.
The Eskimo nebula shows us the gaseous matter spread in outer space by a dead star.
