Description:
The Helix Nebula (also known as NGC 7293 or Caldwell 63) is a planetary nebula located in the constellation Aquarius. Discovered by Karl Ludwig Harding around 1824
It is approximately 655 light years away from us and is one of the closest of all the bright planetary nebulae to Earth.
At its center is a dying star called a white dwarf star. Today, the white dwarf star that sits in the very center of the Helix nebula is about the size of the Earth. Surrounding the remains of the star itself are bands of gaseous matter.
This image was captured in Melbourne using Hydrogen Alpha, Oxygen iii and Sulfur ii filters for the nebula and RGB filters for the stars and consist of a total of over 40h of exposures.
