SH 104 in SHO

SH2-104, is an emission nebula located in the constellation Cygnus, known for its classic bubble-like shape formed by massive stellar winds. In this full-field image, the nebula reveals glowing shells of ionized gas sculpted by stellar radiation, beautifully rendered using the SHO palette (Sulfur-II, Hydrogen-alpha, Oxygen-III).
