Pleasantly surprised to see this on the HN homepage! Our agency (Longbeard) rebuilt this website a few years ago. It was fun working with the great people there, including Br. Guy who is a fantastic ambassador for the VO.
As you can imagine the Castel Gandolfo telescopes are mainly historical at this point due to light pollution, so their VATT facility in Arizona (Mount Graham) is now where most of their actual astonomical work is conducted.
Interestingly, the VATT in AZ is directly adjacent to the LBT facility on Mount Graham, which has a near-infrared instrument formerly named - believe it or not - LUCIFER (Large Binocular Telescope Near-infrared Spectroscopic Utility with Camera and Integral Field Unit for Extragalactic Research).
This was changed to LUCI in 2012 as the name predictably caused some problems and confusion.
