    NGC 2371 / NGC 2372 (Dogbone nebula)
    "Gemini Nebula" is a faint 13th magnitude planetary nebula squeezed between
    Castor and Pollux in the constellation of Gemini. The nebula has a diameter
    of only 0.9-arc minute.
    A long exposed image shows you a bit bright central nucleus and an asymmetric
    rounded structure that surrounds the nucleus. Same as many other planetary
    nebulae, this NGC2371 is an appearance of a dead star with its matter
    gushed out in space. The central star is around magnitude 15.
