This is a photograph of one of the stars measured during the May 29, 1919 solar eclipse to confirm Einstein’s light deflection. The image has been magnified 281 times. The red dot shows where the star’s position should have been had the sun not been present. (Courtesy: Royal Observatory, Greenwich)

Negative of the 1919 solar eclipse taken from the report of Sir Arthur Eddington on the expedition to verify Einstein's prediction of the bending of light around the sun. For positive version, see Image:1919 eclipse positive.jpg.Image:1919 eclipse positive.jpg Original caption: In Plate 1 is given a half-tone reproduction of one of the negatives taken with the 4-inch lens at Sobral. This shows the position of the stars, and, as far as possible in a reproduction of this kind, the character of the images, as there has been no retouching. A number of photographic prints have been made and applications for these from astronomers, who wish to assure themselves of the quality of the photographs, will be considered as as far as possible acceded to.
