McDonald Observatory Domes
The University of Texas McDonald Observatory. The two large domes in the foreground house the 2.1-meter (82-inch) Otto Struve Telescope (left) and the 2.7-meter (107-inch) Harlan J. Smith Telescope (right). Between these two, the Hobby-Eberly Telescope (HET) can be seen, atop neighboring Mt. Fowlkes. Photo by Tim Jones/McDonald Observatory.
