Tivoli became an astro-imaging center in 1986 in preparation for the arrival of Halley's Comet. There are seven permanent observatories on the farm, plus eight piers and miscellaneous concrete pads. The observatories are designed by a German expatriate local to the farm.
Wolfgang Promper came from Austria to train, mentor, problem solve and of course take astronomical images.
Observatories are up off the ground to keep wood from the termites and avoid poor seeing from ground currents.
This observatory is owned by a Russian.
Warm during the day.
Chilly at night

A participant mated his 10" f/3 hyperbolic astrograph to a ProLine PL16803. The results were spectacular - pinpoint star images from edge to edge over a wide swath of the amazing dark southern sky.
