Lecture 26: Telescopes

Telescopes outfitted with modern electronic cameras and spectrographs
are astronomers' primary tools for exploring the Universe. In this
lecture I review the primary types of telescopes and the best
observatory sites to locate them, with a brief mention of radio and
space telescopes. At the end, I give a brief review of the Ohio State's
observing facilities. Recorded 2007 Oct 26 in 1000 McPherson Lab on the
Columbus campus of The Ohio State University.
