‎«In 1839, Harvard Observatory was eventually founded, and W.C. Bond became its first director; in 1847, it was equipped with a 15-inch (37.5-cm) telescope. With this instrument, Bond made extensive studies of sunspots, the Orion Nebula M42 and planet Saturn; in 1848, together with his son, George Phillips Bond, he discovered Saturn's moon Hyperion, at that time the 8th known moon of the ring planet (it was also independently discovered in the same year by William Lassell). William and George Bond were also the first in America to use Daguerre's photographic process for astrophotography: In the night of July 16-17, 1850, they worked with J.A. Whipple, a photographer associated with the Massachusetts General Hospital, to obtain the first Daguerreotype of a star, Vega, a 100 seconds exposure. Consequently, they obtained about 200 to 300 wet collodion plates of the moon, stars, and planets.» William Cranch Bond, né à Portland (Maine) le 9 septembre 1789 et mort à Cambridge (Massachusetts) le 29 janvier 1859, est un astronome américain. Bien qu'il n'ait jamais eu d'éducation formelle, il devient le premier directeur du Harvard College Observatory, où il étudie Saturne et explique la nébuleuse d'Andromède. En 1848 il découvre, avec son fils George Phillips Bond, Hypérion, un satellite de Saturne qui a la particularité de ressembler à une cacahuète. William Lassell fait indépendamment la même découverte. Le père et le fils sont des pionniers de l'astrophotographie, en prenant le premier daguerréotype de l'étoile Véga en 1850 ainsi que la première photographie de la Lune. Jules Verne le mentionne dans son roman De la Terre à la Lune .bon exemplaire .P1-3L‎
