The Milky Way stretching out over McDonald Observatory
The Milky Way looking south from the McDonald Observatory Visitors Center.
At the bottom-left you can see the two of the three big telescopes at McDonald, on top of Mt. Locke - the Harlan J. Smith Telescope on the left, and the Otto Struve Telescope on the right.
The Harlan J. Smith was used for lunar laser ranging in the past, and the Otto Struve Telescope, constructed in 1939, was the second-largest in the world at the time.
