Waxing gibbous moon...

this evening with 78% of the surface visible. Full moon is on Thursday.

Canon 5Div with 500 mm EF lens at 1/125 sec, f/5 at ISO 100.  This is a cropped jpeg right off the camera with no adjustments or sharpening.  I really like this lens.

This Northern Flicker...

was perched on a tree trunk no more than four meters away, basking in the sun and all puffed up for maximum insulation in this frigid weather.

Image shot with my new Canon EF 500mm f/4L IS II USM lens - through an unwashed double-pane window. I’m pretty pleased.

The long flight home...

from one white landscape to another. The numbers: Approximately 9,000 miles on three flights (USH - EZE - DFW - GEG) during a 28 hour long period, not including the final Uber ride. Ugh.

Panoramic view of Stromness...

a historic whaling station to which Sir Ernest Shackleton returned after his epic adventure in 1916. It’s from here that the rescue of the men on Elephant Island was launched.
