Troughton & Simms Zenith Telescope

Troughton & Simms Zenith Telescope

Current location:

Collection Storage Facility

Provenance:

National Research Council Canada

Technical history:

This telescope is a portable instrument intended to measure differences in the angular distance of stars from the zenith (the celestial field above the observer). The telescope allows the observer to determine the latitude of his or her location.

History:

This telescope was used by the Topographical Survey Division of Canada. It was reportedly among the instruments employed in the 1872–1874 survey to determine the 49th parallel, which marks the boundary between Canada and the United States. It was also said to have been used in the railway belt survey that was required when British Columbia joined Confederation in 1871.
