Really interesting place with a very nice interactive area. Standard tour is cheap and only an hour. Note that the town and observatory is in a radio silence zone, your cellphones will NOT work nor is there any Wifi. Digital cameras and other electronics must be shut off before proceeding on the tour up to the actual telescopes so you cannot take pictures unless using a disposable camera (they sell them in the gift shop). You can use phone cameras or other digital cameras from afar, there's even a platform for it.
