On my way back from the Mojave Desert a few days ago, I took a couple pictures of the observatory on top of Mount Wilson. I was surprised by just how many towers and telescopes were up there! One of the telescopes was built in 1908 and was the biggest one in the world at the time!! It didn't look like the visibility was very good, between shooting into the sun and the haze layer, but it gave the picture a very cool effect and you can even see Catalina Island 50 miles away!!
