And from a few of the interesting things within the town, and alongside the highway, they also have quite a sense of humor!

Located about 15 miles away is McDonald Observatory. This premier site is owned & operated by UT Austin, and conducts some of the world's most advanced research in astronomy.
We did the Tuesday nite star party, which started with a nice lecture and tour of the sky from the Visitor Center's ampitheater, followed by viewing through a dozen telescopes set up at the Center ranging from 8 to 20 inches.

The following day, I went on the excellent tour of the 107 inch Harlen Smith telescope and the new 400 inch Hobby-Eberly. The orginal telescope at the site, an 82 inch reflector, was installed in 1929. It and the 107 inch companion sit atop a 6800ft peak just above the Visitor Center. To give you some concept of size, here's the 82" with vehicles parked out front.





The 107 is a massive instrument, used mostly today for taking critical spectral images of distant stars and laser measurements of minute distance variations to the moon.


The tour was completed with a visit to the newer 400". This is a "low cost" design utilizing multiple mirror segements rather than a single mirror (impossible at 400"!). The entire mirror assembly is rotated effortlessly on six "air bearings" on it's bottom ring.
