Nestled in Burnet Woods is the Trailside Nature Center, and nestled in there is Wolff Planetarium. It's open very infrequently-- they do planetarium shows maybe twice a month-- but it's worth visiting if you get a chance.
Our show was about Orion-- the guide told the mythological stories about him, showed us where he lays in the sky at different times of the year, and pointed out other constellations around him. The show was an hour and only $3/person.
