Bjørn, Jacov, Elsa, Erik, thank you.
Bjørn, the lens was the Fuji 100-400 on the X-T2. It was at 400mm, f5.6, 1/280 sec, ISO 400. The camera was handheld, braced against the window frame.
I did crop in quite a bit. Here is an uncropped original of the first for comparison. On the whole, I think the lens and camera did well in the circumstances.
