McDonald Observatory 2018 Visit

We visited McDonald Observatory in Fort Davis on our trip to Big Bend National Park -  where we would work for the Summer.  After leaving Enchanted Rock State Natural Area, we camped at Davis Mountains State Park for the weekend and had Sunday to visit the observatory.

Below is a view towards McDonald Observatory from highway TX-118Mt. Fowlkes is on the left and Mt. Locke is on the right. The Hobby–Eberly Telescope dome is visible on Mt. Fowlkes and the domes of the Harlan J. Smith Telescope and Otto Struve Telescope can be seen on Mt. Locke.

McDonald Observatory is a 15-minute drive from Davis Mountains State Park; so the State Park is the perfect place for an overnight stay when you want to visit McDonald Observatory.




Timing is everything when headed to the Observatory if you want to catch a tour, Star Party or Twilight Program. They have scheduled tours twice every day of the week and Star Parties and Twilight programs available Tuesday, Friday, and Saturday (check the tour page for exact details and times).

Since we were there later in the day and on a Sunday we didn't get a tour or Star Party, however, the guide at the visitors center explained the closing times for the 3 main telescopes (5 p.m. I believe), and we were able to do the self-guided tour of the three main telescopes.  

We definitely plan on coming back for tours and a star party or two but just getting to go into the display lobby of the Hobby–Eberly Telescope (HET) was amazing. We were able to do some reading, begin to understand how it all works and view the interior of the telescope.

HET is composed of 91 hexagonal segments, using a segmented mirror design.  The segments function together as a single curved mirror.  


We were also able to walk around the building containing the Otto Stuve Telescope, the first major telescope built at the McDonald Observatory. 


The wording on the Historical marker outside the Ott Stuve Telescope begins with "Original unit in a complex forming one of the great observatory centers in the world".

We also were able to go into the small display room of the Harlan J. Smith Telescope and read about its history.

The views from the top of Mt. Locke were amazing and made us appreciate even more what we have here in Texas at McDonald Observatory.
