Chabot Space & Science Center

High in the Oakland Hills, the Chabot combines a superbly equipped, state-of-the-art planetarium with an observatory and film theatre; the latter runs 70mm projections of the internal workings of the human body or the cosmos, seen at both the largest scale and the submolecular level. The three telescopes here include a 36in reflector telescope that is housed in the rotating roof observatory; you can look through all three most Fridays and Saturdays, depending on the weather conditions.
