I drove up to Palomar Mountain yesterday to scout around for skygazing sites, and I was surprised to find out that Caltech's stewards of the 200-inch telescope had finally opened up the observatory to visitors again. So as long as I was there I popped in. I was unable to get a good picture of the telescope itself, but it was a fine clear day for photographs of the dome.
The exterior is astonishingly clean. How do they do it?
That's when they were building for eternity.
