Interesting details Denis.
I stayed in this hotel a few months ago and the hotel manager gave a brief of the observatory one evening. I didn’t know it was there until spotting it on arrival, so it turned out to be a nice bonus to the few days in the area. Attached are a few images showing info about the telescope displayed in the hotel. It looks similar to what you posted Denis, but also has some different info (I notice Dave Gavine gets a mention).
I’ve also attached an image of a rather nice sundial that is located above the entrance to the hotel.
