The Helix Nebula (NGC 7293), aka Helical Nebula or Sunflower Nebula, is a planetary nebula found in the constellation Aquarius. Despite it's designation as a "planetary" nebula, it has no relation to a planet. The term planetary nebula came from the "appearance as a planetary disk" in early telescopes. Planetary nebula are indeed the expelled gaseous remains of aging stars. The image is a total exposure of 1 hr 40 min (20 X 300 sec) taken with a Takahashi E-180 and Canon 20Da DSLR camera.
