Well the closest club to me, is my own astronomy society. I am the president of CWAS (central wyoming astronomical society) www.cw-as.com
Aside from us, there is the Laramie Astronomy Society, The Cheyenne Astronomical Society, and coming soon I think is the Fremont/Riverton Astronomical Society. They are coming to my night sky observation on the 26th of this month to learn what it takes to have a club. Gillette also has one now, as well does Jackson Hole, but I never hear to much about Jackson Hole so I am not sure if they make themselves public or not.
But I digress....I was just letting all my fellow locals know of my solar observation at the beartrap summer festival this weekend. We will be enjoying bluegrass music all weekend while checking out the sun through the coronado PST. I am raffling off a pair of 7x50 nikon binocs, as well as 50% of a 50/50 drawing. The weekend will be wrapped up on Sunday night with the Nitty Gritty Dirt Band playing at the festival. Also I have a public night sky observation set up for the 26th of this month at a location outside of Casper. It gets very dark and awesome there........providing the wind isn't blowing. Last year we got to see the milky way so bright, it was casting shadows.
let the festivities begin.
