Brief Description: Collodion glass negative, with cover-glass and mat with circular aperture, wood framed in the manner of a lantern slide. The Moon at 20 days, photographed with De la Rue's 13-inch reflector with a 14-second exposure. Good surface detail. The moon's disc is 1 and an eight inches (29mm) diameter. Martinus Hoek (1834-1873), professor of astronomy at Utrecht and best known for his study of comets, was presumably visiting the private observatory of De la Rue, who was England's foremost astronomical and lunar photographer at the time; the 13-inch reflector later came to the University Observatory, Oxford.
Primary Inscriptions: Various inscriptions scratched on the negative, including '1865' and 'in presence of Prof Hoek'; dot labels on mat inscribed '20 days' and '1865 Aug.11. 14 sec'.
Provenance: Transferred from the University Observatory, Oxford.
