The skies at Crater Lake National Park are so dark. This was just a day or two before the new-moon phase so I had until about 4am of dark skies to take photos before the moon was going to rise. Shooting during these conditions is hard since there is nothing lighting your scene, but there's a few tricks that I'm still learning about to deal with that.
This photo is composed of two different exposures. I shot the sky at f/2.8, ISO 3200, and exposed for 30 seconds. For the bottom half I shot it at f/2.8, ISO 3200, and exposed it for 4 minutes. I lit the little piece of foreground with a flashlight.
