The Omega Nebula (also known as the Swan Nebula, the Horseshoe Nebula, the Lobster Nebula, Diffuse Nebula M17, Messier Object 17, Messier 17, M17, or NGC 6618) is an emission nebula in the Sagittarius constellation.

Messier marathonMessier marathon is an attempt undertaken by amateur astronomers to find as many Messier objects as possible during one night. The Messier catalogue consists of 110 relatively bright deep space objects ( galaxies, nebulae, and star clusters).

The longer dimension is oriented in an east-west direction. Just to the west lies Messier A
