SH2-54 & NGC 6604 - June 2020
Sh2-54 is an extended bright nebula in the constellation of Serpens.
In its core there are many protostars and many infrared sources; some of these sources, like IRAS 18151−1208, are most probably very young high-mass stars. The older star population in this region has an average age of 4-5 million years, and its components are grouped in the open cluster NGC 6604.
Sh2-54 belongs to an extended nebulosity that includes also the Eagle Nebula and the Omega Nebula. The young high-mass stars of this region constitute the Serpens OB1 and Serpens OB2 OB association.
Because of its proximity to The Eagle Nebula, this area appears not to be imaged very often - but I found it worth the effort in order to show this very active and beautiful area of the sky.
