Movement of the planet I'm standing on caused the stars to appear as streaks. (This is a stack of 142 x 30 sec, ISO 640, 18 mm, f/6.7). This was shot in the dark skies along the Blue Ridge Parkway. Thirty-three years earlier I had bicycled this wonderful ribbon of asphalt through the mountains. In the interval, these same stars circled the polar axis nearly 14,000 times.
