This is why some people don't sleep after dark. Says Goodwin:
I was surprised to find so few shots of iconic Priest Lake under the stars so I went up last night to see if I could find a good location. I also wanted to try out star pictures on a lake.
The stars were stunning the sky was more colorful than I expected. I'm not sure what the green and purple are. Perhaps aurora borealis. They ebbed and flowed while I was out, with the pink in the lower left disappearing quickly.
I know it looks like I just cranked the saturation but this is pretty close to what came out of the camera at f2.8, 3200 ISO, and 30 seconds exposure.
