Harlan J. Smith Telescope, Research telescope at McDonald Observatory in Davis Mountains, Texas.
The 107-inch Harlan J. Smith Telescope contains a primary mirror measuring 2.7 meters in diameter and weighs 160 tons within its 23-meter dome.
The telescope became operational in 1968 as the third largest optical reflecting telescope worldwide, constructed with NASA support for planetary space exploration.
The McDonald Observatory facility welcomes researchers and astronomers from the University of Texas at Austin to conduct studies of stars and distant galaxies.
Located at coordinates 30°40'18"N and 104°01'19"W, the telescope performs observations every clear night using specialized instruments for astronomical measurements.
In 1970, the telescope mirror sustained damage from gunshots by an employee, yet continued functioning effectively for astronomical research and discoveries.
