The Helix Nebula, designation NGC 7293 is the largest and closest of the bright planetary nebula and lies in the constellation of Aquarius. It lies approximately 655 ly from earth and has an apparent magnitude of 7.6. It is formed by an intermediate to low-mass star, which sheds its outer layers near the end of its evolution. the central star, which is destined to become a white dwarf, is so energetic that it causes the previously expelled gases to brightly fluoresce. A full colour camera image captures wonderfully both detail and the different colours that make up the classic “eye” shape. Another well deserved place in our “Klein & Fein” showcase.
