With weather looking wet and wild for the 2019 Cherry Springs Star Party and things looking slightly less soggy at Calhoun we decided to cancel on Cherry Springs and gamble on Calhoun. Good thing we were setup on the top of a ridge so we never had to deal with muddy conditions considering all the rain we didn’t know was coming.

The first couple days were all clouded out.
Night time conditions were very soupy
Couple nights later things were improving but still very humid and hazy. The Milky Way was at least starting to pull out of the haze.
Cloudy rainy days
Equipment setup and hoping for clearing

Finally some stars poking through the clouds. Look at that new bright light in the East / NE; it’s really projecting up!
