Map of the moon by H Percy Wilkins, third edition, 1952 Long Caption: One of twenty-seven sheets forming H. Percy Wilkins' 300 inch Map of the Moon, Object ZBA4573. This is the printed 3rd edition of 1951, in an impression that includes additional details discovered in April 1952 with a 33 inch Meudon Refractor. It is an orthographic projection at mean libration at a scale of 21.6 miles per inch. This edition was based on the drawings of the 1946 edition (ZBA4447), which were compiled from "the finest photographs, drawings by the most current observers and as a result of personal observations commencing in 1909, with telescopes of various apertures, but chiefly with a 12 1/2 in reflector", and based on the measurements of S.A. Saunders and J. Franz. The index sheet of this edition was compiled by P.A. Moore FRAS. Wilkins was a fellow of the Royal Astronomical Society and Director of the Lunar Section of the British Astronomical Association. His map of the moon was the most detailed lunar chart produced before the space age. Credit line: © National Maritime Museum, Greenwich, London Object: ZBA4573.14 Artist: H.
