It was a cracker of a night that is for sure Steve. I was up at the observatory at Mapleton, where it was 9 degrees inside (with 3 of use keeping the temperature up with our body heat) with about a -200 degree windchill factor outside.

Man it was bitterly cold outside. Easily 25 knot SWers. As soon as I walked outside I started to shiver, and that was with 5 layers on. I thought we might lose one of the dome flaps at one stage.
But I could have reached out and grabbed the milky way it seemed so close and clear. True seeing was atrocious, but the transparency was absolutely awesome. One of the clearest nights I can remember. Made the frost bite worth it.
