In 1867 Henry Draper built himself a second dome at his Hastings on Hudson observatory to house a larger telescope with which to photograph the heavens. His detailed photographs of the moon (seen pinned to the wall on the left) garnered him an international reputation, after which his observatory became a pilgrimage site for scientists. This sourvenir photograph, commerically printed in New York, included a caption that gave the details: "Interior of the Equatorial Room of Professor Henry Draper's Observatory, at Hastings-on-Hudson, near New York. Latitude 40o 59' 25"; Longitude 73o 52" 25" West of Greenwich. Showing the 28 inch Silvered Glass Reflector: the 12 inch Achromatic and the 5 inch finder."
