NGC 7293 -- Helix Nebula
The Helix is a "planetary" nebula - an expanding shell of gas which was ejected from a red giant star nearing the end of its life. The central star is then destined to become a white dwarf.
The Helix lies 700 light years distant within our Milky Way in the constellation of Aquarius.
This image was captured under high desert skies near Santa Fe, New Mexico, USA with a telescope of 12" aperture at f/8 and an electrically-cooled CCD camera.
