This is M17, the Swan Nebula in the constellation Sagittarius. M17 is
also known as the Omega Nebula and is about 5,000 light years away.
Visually the brighter portions of this nebula take on the profile of a swan
swimming on a mill pond and make one of the more spectacular summer nebulae
visible from the northern hemisphere. This image has been rotated by
180 degrees to better show the profile of the swan so north is down.
