The skyBuilders logo image is based on a colorized version of a medieval woodcut sometime ascribed to the astronomer Camille Flammarion. Flammarion added the Sombrero Galaxy (image on our home page) to the original Messier Catalog as M104. There are many colorized versions of this woodcut on the web. Ours is based on an anonymous source. Many other versions are cited by Kerry Magruder.
