Photograph showing a pastel drawing of the Omega Nebula, a feature often today called the Swan Nebula. Etienne Leopold Trouvelot (1827-1895), a French artist and the astronomer, Prof. E.S. Holden (1846-1914), together produced this sketch in 1875. It is based on observations made at the United States Observatory at Foggy Bottom in Washington using the 26-inch Clarke refracting telescope. Visible in small telescopes, the nebula was first recorded being observed in 1745-6 by Frenchman, Philippe Loys de Cheseaux. Located in the Milky Way, it consists of a large glowing cloud of hydrogen gas.
