It's amazing what you can find on the streets of San Francisco. No, the actual city streets, not the '70s cop drama starring Michael Douglas. I recently came across a scavenger's treasure in the city's Sunset neighborhood: a fully operational Meade NG-70 Altazimuth Refractor Telescope. It was just sitting there on the curb with a handwritten note simply stating "Free" taped to its barrel. Now, I'll tell you, I'm not much of an astronomer -- inasmuch as I have never used (even touched) a telescope or ever had much interest in learning. The idea of standing around outside in the dark, fiddling with dials always seemed too much hassle to make very distant sparkly objects to appear slightly larger. But what I am also not is a sucker -- and a free telescope is a free telescope -- so into my car's trunk it went.
