Old observatory in Toronto in 1880 with a Cooke telescope

 The University of Toronto’s David Dunlap observatory at Richmond Hill near Toronto, Canada today houses a 74 inch Grubb Parsons reflector that was installed in 1935. However there was a much older observatory in Toronto. 

This was the Toronto Magnetic and Meteorological Observatory at the University of Toronto which  housed a 6 inch Thomas Cooke & Sons telescope that was installed in 1880. The Cooke was used in particular for the study of sun spots in conjunction with magnetic measurements made at the observatory. I believe that the Cooke may have been used until around 1910.
