I was up in the San Juans last weekend. Thought I'd try out some long exposure shots with my new A900. This is a 13 minute exposure @ 400 ISO. The moon was about 3/4s full and I was pointing out of American Basin (north). That bright cabin in the center of the shot is right off the Cinnamon Pass road, part of the Alpine Loop.
I should have done it at ISO 200 or 100, but I didn't want to babysit the camera for an hour (30 min exposure and 30 min dark frame) or 2 hours at 100.
