In the video for the Extremely Large Telescope Haran stands at the site of the future ELT and looks down off the edge at another observatory, and says a little after
There are a couple of other little observatories around here. There's one run by a local university here in Chile, and that one there is run by Germans; cool little spot. Apparently there's usually someone there. How'd you like to be working there alone?; middle of nowhere.
Another interesting fact actually, this mountain was *almost chosen as the site for the VLT, which ended up over there. So you know it's pretty good for telescopes, and finally it's going to get one, when they build the E-ELT.
Question: What two "little observatories" run by a university in Chile and "by Germans" are near the future site of the Extremely Large Observatory? And when were they built?
