This "skies are clear but the outside of the dome is dripping with condensation" situation is fairly common at SIding Spring Observatory in winter. I've experienced it many times before, with the AAT, UKST and Huntsman Telescope.
The telescopes here do generally stay open at higher humidities than at many other observatories, but even they have their limits.
