Hale telescope
In order to regain prominence in the field of astronomy, in 1963 the Director of the DAO Dr. R. M. Petrie proposed the construction of a national observatory, with a 3.81 m (150 inch) telescope as the primary instrument. Upon completion, this would have been the second largest telescope in the world, the only larger telescope being the 5.08 m (200 inch) Hale telescope at Palomar Observatory in California.
