Mars

Four of us went to campus to try to see Mars Wednesday night. The line for the observatory was easily a block and a half long, and I found out the next day that they only took the first 200 and turned back at least 300. Luckily I remembered the old observatory on top of Sterling.

I called from my office to say where we were going, and yep, the light was on in the dome. Up to the roof, where a stiff breeze was making the youngest daughter bitterly regret her summer outfit. Alas, the grad student manning the refractor hadn't used it before, and was yanking it this way and that staring through the main scope. Someone more experienced suggested that using the spotter scope was a good idea, as was putting eyepieces in the various scopes. (Yes, he had taken the lens cap off.) Still no joy. I was close to offering my services when a researcher took pity on us and offered to let us look through his scope in a nearby dome. His was a much more compact reflector, but with twice the diameter.

He tried to show our little group of 17 a globular cluster first, but my youngest son was first in line, couldn't see well, and grabbed the scope for balance. Sic transit globular cluster. The dome rotated smoothly around as the long-suffering researcher looked for Mars. He spent most of his time punching buttons on some kind of special calculator, which I guess must translate coordinates and time into a direction for the scope.

The magnification was no bigger than on our little scope at home, but it was far brighter, and the colors weren't those of the rainbow. Mars was clear and beautiful--wobbling a bit because of the wind shaking the building. We all looked a couple of times, thanked our host, and trekked our separate ways.

And, of course, what better treat to end an outing with than ice cream?
