NGC 7293 or more commonly known as the Helix Nebula or Eye of God or Eye of Sauron is a planetary nebula formed by the expanding shell of glowing gas around a dying low-mass star. It is located in the constellation Aquarius and is about 650 light-years away with a diameter of about 2.5 light-years. Went starless with this one to highlight the nebulosity, especially the outer shell.
33 x 20min and 147 x 5min SHO subs shot @-10C taken over 9 nights for an integration time of about 23 hours.

Oh man.... and just when I was happy with my capture of it, you blow mine completely out of the water Carlos! :)

Well, you are giving me something to shoot for once again, as I really love all of the detail in this. The eyebrow is so cool, I could barely make that out in mine. Well done!
