M17 - Omega Nebula
-----------------------
The Omega Nebula (or 'Swan Nebula') is one of the brightest and largest star-forming regions in our galaxy, around 40 light-years in diameter.
The radiation emitted by the cluster of young stars in the center of the nebula ionizes the interstellar gas around it, which makes the nebula visible.
The nebula contains around 800 stars, including 2 blue hypergiants (the pair of bright stars on the left of the image) which are more than 200,000 times more luminous than our Sun.
This is the result of a total of 16 hours of data (in H-alpha & color), captured in May-June 2020.
