NGC6888 - The Crescent Nebula

Description:

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.
