Sh 2-54 is an extended bright nebula in the constellation of Serpens.

[1] 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.

[4] 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.

[2] Sh 2-54 belongs to an extended nebulosity that includes also the Eagle Nebula and the Omega Nebula.

[5] The young high-mass stars of this region constitute the Serpens OB1 and Serpens OB2 OB association.
