Lagoon and Trifid Nebulae in HaRGB

This picture shows off a wide view of the starfield in the Sagittarius constellation. While evidencing all the dark nebulosity in contrast with the yellowish stars in the background of the Milky Way core, it highlights the HII regions in the field, such as Messier 8 and NGC 6559 as well. The picture is also full of star clusters, being Messier 20 the most colorful of all, as it is a star cluster associated to both emission, reflection and dark nebulosity.
