Second attempt at observatory, it has a warm room/sleeping unit 3.6 x 3.0 metres amd a telescope room the same dimension. The warm room is fully insulated and has cooking facilities and a heater, night time temperatures in the winter can get to -15C and that doesn't include the wind-chill factor. Construction is 100mm x 100mm posts clad in 12mm H3.2 ply. Main power supply is a 6.5 kv generator, when this pic was taken I was starting to experiment with the idea of remoting the site and using Solar Power.
