Wintertime Backyard Night Sky Over New Jersey.

The night sky was clear and I haven’t done star trails for some time. I set up a Nikon D850 camera with a 8-15 mm fisheye lens (ISO 800, 15 mm, f/8, 30 sec) on my patio to collect a series of night sky images. The images were processed with Capture One Pro and the composite star trails created using Photoshop CC (scripts, statistics, maximum).

Thirteen-Years Ago (29-January-2007) — Norway

Gone to See Norway 2007 Family Winter Vacation. Day 9: Hurtigruten MS Kong Harald Norwegian Coastal Voyage Northbound (Båtsfjord to Kirkenes) then Southbound (Kirkenes to Berlevåg).

There were a dozen or so Black-tailed Ducks swimming in the icy waters as we departed Kirkenes, Norway on the Hurtigruten MS Kong Harald. It was cold enough out that ice was forming on the surface of the salt water.
