Backyard Winter Dawn Sky in New Jersey.
Somewhat of a repeat post from last Thursday (25-January-2018).
There were some subtle colors in the sky at dawn. I used a Leica T camera with a wide-angle zoom lens (11-23 mm). There is significant distortion when the lens is used at 11 mm. For comparison, the first horizontal image is at 11 mm, and the 2nd image is a composite of 5 vertical images at 18 mm.
