    The tour guide had a lot of information of the building and its history. The architectural beauty is something not seen often and each piece is part of a bigger story.  more »

    One of the best observatories I've been to. They have tours and the will move the big telescope, the dome and the floor so you can see how it works. So much fun! The speakers are awesome and have so much knowledge. They have a gift store and you can buy some astronaut ice cream as well. They have a book that talks about the best locations and details for the 21st August eclipse that has 2 eclipse shades gift inside!

    Excellent-what an experience-difficult to grasp the enormity and complexity of our universe. Standing where Hubble, Einstein and Sagan studied is truly humbling. There simply must be other life forms out there!

    Took a group for a viewing/tour and although the weather didn't cooperate for using the telescope, the tour itself was wonderful. Dan Koehler was a fantastic tour guide, telling the story of this amazing and beautiful building and the awesome instruments it houses. I cannot recommend the experience highly enough.

    Personally too much time spent on architecture of building. Found it a little boring.
