Solar eclipse observed by Maxwell Lyte at Sencours Pass on July 18, 1860 These photographs were taken at the hostel of Sencours, at an altitude of 2365m, by Maxwell Lyte. Alexis Sajous, photographer in Bagnères-de-Bigorre, was his assistant. A refractor of about 3.50m had been installed in a makeshift hangar (boars and metal sheets) near the hostel. A narrow opening let the solar light reach the lens, and the photographs were taken at the focus of the telescope without any magnification. The diameter of the photographic image of the sun corresponds indeed to a focal length of 3.60m. According to Mr. Sajous, the installation had been painstaking. The photographs were taken by very good weather, whereas the inferior clouds, completely covering the country, reached 2200 or 2300m. It was raining below these clouds. - MédiHAL Accéder directement au contenu

Eclipse de soleil observée par Maxwell Lyte au col de Sencours le 18 juillet 1860. Ces photographies ont été faites à l'hôtellerie de Sencours à 2365m d'altitude par Maxwell Lyte. Alexis Sajous, photographe à Bagnères-de-Bigorre, avait été l'aide de Maxwell Lyte. On avait installé une lunette astronomique de 3,50m environ dans un hangar improvisé (planches et tôles) à côté de l'hôtellerie. Une ouverture étroite donnait accès à la lumière du soleil sur l'objectif, et les photographies furent faites au foyer de l'objectif sans agrandissement. Le diamètre de l'image photographique du soleil correspond en effet à une distance focale de 3,60m. D'après Mr. Sajous, l'installation fut très laborieuse. Les photographies furent faites par très beau temps, alors que les nuages inférieurs, couvrant totalement les plaines, arrivaient à 2200 ou 2300m. Il pleuvait sous ces nuages. L'exemplaire de l'observation porte que les plaines étaient "battues par la pluie".
