Light pollution has taken its toll. The University of Toronto has announced the closing of the David Dunlap Observatory. Originally this observatory was on a farm site 25Km north of the city limits. It is now encircled by the city known as the GTA- Greater Toronto Area.
When opened in 1935 this observatory housed the second largest scope in the world (1.88 meter) The mirror was cast by Corning and I believe was the first ever to use a pyrex type of glass.
