Photographic plate by Stewart taken from the 'Illustrated London News'. In the 19th century, expeditions were dispatched around the world to make scientific observations of eclipses. American astronomers from the Lick Observatory, California, travelled to Jeur, in the Maharashtra region of India in 1897 in order to observe the eclipse which occurred on 22nd January of the following year. Astronomers from the Observatory transported their 12 metre long eclipse telescope and its attendant camera to observe virtually every total eclipse of the Sun that happened between 1893 and 1931, visiting every continent bar Antarctica in the proces. This photograph shows the telescope being operated by Profesor Campbell.
