    I came here with my daughter, she absolutely loved it. It was amazing to experience the night sky come alive as it does here. Truly makes you wonder at the size of our universe and how small a part of it we occupy. Hope to return again soon.

    I came here on a school trip a few years ago and it was a very interesting experience. I've always been fascinated by stars and space in general, so to be able to see this observatory was certainly a unique experience. Very cool for anyone who is interested in space!
