We went up one evening for night sky viewing and were really impressed. The telescopes are something like 130 years old, and it's a real testament to their craftsmanship that the viewing was awesome. (Of course I don't have a lot to compare it with, but still) Very mixed crowd - couples, singles, people with kids, and the sweet couple in front of us who seemed to be on a first date. The line for the viewing looked long but went quickly. Afterwards we went inside and took a look at some of the exhibits - at least what was accessible in the evening. Lots of engaging stuff for kids. Definitely recommend.
