In particular, note that the Chabot Space and Science Center in Oakland,
mentioned in the above, in addition to educational facilities has Friday
and Saturday evening public viewing through their 8, 20, and 35 inch
telescopes as well as private amateur telescopes set up by volunteers on
the sky observation plaza. Very good for beginning amateur astronomers
and fun for established amateur astronomers.
