From the you-think-that's-bad department......Florida Panhandle here. In August, 90% humidity would be considered arid. Just in case the unimagineable occurs and the sky clears up for one evening, we have Ninja mosquitoes just waiting for us to be foolish enough to set up scopes and cameras. In all my years here, I have once and only once enjoyed astrophotography on an August night. It was while a hurricane was crossing central Florida and sucking dry air over Pensacola, dropped to the low 60's that night, it felt frigid. A few weeks later we were hit by Hurricane Ivan, took out the U.S. Interstate 10 bridge over the bay and knocked out power for weeks. But oh how gourgeous the skies were after that.....dark, clear, no light pollution. We slept in the screen room because it was too hot in the house, I still recall seeing the Pleiades rising through the branches of the leafless trees in my back yard.
