With photographs taken by the Henry brothers on their photographic telescope, including three heliogravure plates (one folding), four original photographs with overlay keys, and some wood-engraved illustrations in text. Rebound in red leather over original wrappers. Admiral Mouchez's equatorial photographic telescope was specifically constructed to create his photographic map of the heavens. It was possible to photograph extremely faint stars with the newly developed silver bromide-gelatin plate. The first photograph, which serves as a frontispiece, is of the lunar surface in the region of the crater Eratosthenes. The second is of the Hercules cluster. The third photograph is a time-lapse series of images of Jupiter, showing the rotation of the red spot. The fourth is of Saturn and its rings and of Jupiter and its bands.
