CHRISTINE CLEMENT's RESEARCH
with the HELEN SAWYER HOGG TELESCOPE
at LAS CAMPANAS, CHILE
The Helen Sawyer Hogg telescope was a 24-inch Cassegrain reflector set up in Chile in 1971 by the University of Toronto. It was located at the Observatory of the Carnegie Institution of Washington, on Las Campanas, one of the best sites in the world because of its dark, clear skies. The telescope remained in operation until 1997.
