Description

Captured over the following nights: June 21, 26, 29-30 and July 1.

--- Reprocessed using tone mapping while adding RGB stars. I had some spacing issues with my ASI, so there's plenty of elongated stars in the corners. Using StarNet in PI to remove stars left some artifacts in the image, but it's an improvement over my original with bloated stars.

M16, the Eagle Nebula, is a star cluster around 2 million years young surrounded by clouds of dust and glowing gas. It is about 7000 light years from Earth. The largest dense, dusty columns described as “Pillars of Creation” are light years in length, but are gravitationally contracting to form stars. Energetic radiation from the cluster stars erodes material near the tips, eventually exposing the embedded new stars. To the left of the pillars is another dusty star forming column or spire known as the the“Fairy of Eagle Nebula.” The small dark areas are believed to be protostars (Bok globules).
