To find truly dark skies, go north. My friend John Walsh, an avid backpacker, headed to the northernmost part of our state for a fall weekend adventure. I convinced him to take my camera and film, explained how to attach chemical handwarmers to the lens to keep it from fogging over, and asked him to open the shutter for six hours when he got there. Among his other nice photos of aurora and bright stars, is this beautiful picture across a gently flowing stream, reflecting the night sky and the northern lights.
