Here is the final stacked and post-processed image of Messier 16 (Eagle Nebula) using Vixen ED115S mounted on Skywatcher EQ6 Pro mount, and ZWO1600MC-cool camera taken last May 19-20, 2018 from Al Sadeem Observatory by resident astronomer Aldrin B. Gabuya.

The Eagle Nebula, known as Messier 16 (M16) or NGC6611, is a prominent deep-sky object which consists of a cluster of young stars with surrounding interstellar cloud of gas and dust. Discovered by the Swiss astronomer Jean-Philippe de Chéseaux in 1745-46, it is an active star-forming region, particularly an HII diffuse emission nebula situated in the constellation of Serpens (the snake). The dark silhouette near the nebula’s center resembles the shape of an eagle and a “Star Queen” as described by the American astronomer Robert Burnham Jr., in which the names were derived.

Estimated about 5.5 million years old, this nebula is about 7,000 light years away from Earth, with a radius of 70×55 light-years, with its bright cluster of young stars spanning about 30 light years in diameter.

This nebula is known for the wonderful “Pillars of Creation” which is a large star-forming region composes of huge dense gas clouds at the heart of the nebula. Hubble Space Telescope photographs taken by Jeff Hester and Paul Scowen reveal small dark protostars known as Bok globules. Few X-ray sources observed from NASA’s Chandra X-ray Observatory suggest that star-forming within the cluster is at its last phase from the idea that newly born stars produce tons of X-ray activity.

With an apparent magnitude of +6.0, the Eagle Nebula is easily found in a clear dark sky, using the Teapot asterism in Sagittarius, along with the line drawn from Kaus Australis to Kaus Media. It can also be spotted about 2.5 degrees west of Gamma Scuti or slightly north of Messier 17 (Omega Nebula). Small telescopes of about 4-inch diameter can reveal about 20 stars with surrounding nebulosity. Large telescopes of diameters of 12 inches and above can nicely resolve the Pillars of Creation.
