Another Scottish Cooke
John Robertson of Coupar Angus 1830-1920 owned a fine Thomas Cooke of York 3 inch refractor telescope. His interest in astronomy began in 1848 when he heard Dr Thomas Dick give a series of astronomical lectures.
He spent many hours observing the sky, including sunspot observations and comets and meteors. He was self educated and he had to fit all his observations of the sky around his work. He was employed by the Caledonian Railway.
He sent many articles to newspapers including the Scotsman and some of the Dundee Daily newspapers. Among the astronomers he correspond with were Sir W.H. M. Christie, Richard A Proctor, Sir Robert Ball and Ralph Copeland.
He was still using the 3 inch Cooke telescope as late as August 1917 to observe sunspots, with his advanced age his daughter had to help move and adjust the telescope.
