Star Trails
Star trails on a clear but somewhat hazy suburban Mid-Atlantic (read bright sky) early Fall night. Testing a new lens for night sky shooting: Nikon 20mm f/1.8. Looks like a winner: sharp, fast, and light, slight coma distortion in the corners wide open, but much better than the 15mm lens I had been using, though of course not quite as wide. 139 frames, 20 sec. each, f/1.8, ISO 400, totaling 49 min. (short exposures to keep the brightish sky relatively dark). Stacked in Ps CC.
