star-gazing

badastronomy was right: a green laser pointer is an amazing tool for stargazing purposes. Sadly, my particular one doesn't like the cold weather and eventually stops working (though it was briefly shone a weak red... that was kind of weird). Also, lunar eclipses are neat.

Betelgeuse is also surprisingly red. I don't know that I'd noticed that before. I mean, it is a _red_ supergiant, but.. its really red.
