NGC6888 - The Crescent Nebula


The Crescent is a beautiful tangle of all the elements we astrophtotographers love. The nebula is a result of competing stellar winds shed from the internal Wolf-Rayet star.
This type of star is evolved, or late in its life. It is fusing heavy elements and blown-off most of its Hydrogen and Helium outer atmosphere due to its intense energy production. This gives rise to the delicate and fascinating structure of the surrounding nebula.
The red tones represent hydrogen gas emission clouds. The aqua blue areas are emissions of oxygen.
