I believe the one in SF is attached to the observatory, that is either in fog or very clear.. installing such a beast in the polluted populated Sacramento valley would be a waste of resources. Go to Hawaii instead
The Planetarium is a domed theater. The weather doesn't matter.
They put on educational shows on the planets, stars, solar system, etc.
They used to do a show called Laserium, which inolved dancing lasers in creative patterns, set to a wide range of music, from Strauss to Pink Floyd.
I took my wife to see it on our first date, November 1975.
