Messier-17 has several names: the Swan, the Omega, the Horseshoe. It is an intense star-forming region that is nearby, on a galactic scale (5,000 light years distance).
The predominant pink colour suggests hydrogen heated by several intense young stars in the bright centre.
Our eyes are drawn to the swirling dust and gas surrounding the intense core of the nebula.
I photographed Messier-17 from my balcony in Strasbourg France on three nights in July 2023. This is a composite of 57 x 3 minute exposures.
