Originally produced for Planetaria or dome-ceiling theaters this video is a good introduction to
some of the history behind the development of the telescope, and how some of the newer optical technologies are changing the way astronomy is done and the
types of remote data we are able to collect. Told by a science Teacher with two of her students as they use a large Dobsonian telescope at a star party.
