Omega Nebula

The Omega Nebula is also known as the Swan Nebula and designated M17 in the Messier catalog of celestial objects. It is one of the brightest and most massive star forming regions in our galaxy.

The Omega Nebula is located in the Sagittarius constellation some 5,000 to 6,000 light-years from Earth. the main part of the nebula is about 15 light-years across and the larger cloud of gas and dust that makes it up is up to 40 light-years in diameter. This cloud is estimated ot have a mass of some 30,000 time the mass of the Sun.

There is a cluster of stars embedded in the nebulosity that causes the nebula to shine from the radiation from these hot, young stars.

The image was processed from a “pro data set” captured by Nick Szymanek with the Planewave CDK24 telescope at the El Sauce Observatory in Chile. I processed the luminance, red, green and Blue image data using Pixinsight and Photoshop.
