Oops, I almost missed this: a PBS show called "Journey to Palomar" will be on tonight (check local listings). The blurb sounds pretty good for astronomy nuts (aka BABloggees):
The story of American astronomer George Ellery Hale (1868–1938) and his efforts to build the world's four largest telescopes — which set the stage for astronomy and space exploration throughout the 20th century, revealing the greatest discoveries since Galileo and Copernicus. Hale's lifelong struggle to build these great instruments culminated with the million-pound telescope on Palomar Mountain.
I think I may have already missed it; it's not playing in my local area. But you may be more fortunate. Check it out, and if you see it leave a comment!
