ASTRONOMY - Cathedral - Mountain - Moon

 2023 December 25

A tree-lined hill is shown topped by a majestic
cathedral. Directly behind the cathedral is 
of a triangular-shaped mountain top. Directly behind
the mountain is a crescent moon, although the exposure
is long enough to see the rest of lunar circle. 
Please see the explanation for more detailed information.

Explanation: Single shots like this require planning. The first step is to realize that such an amazing triple-alignment actually takes place. The second step is to find the best location to photograph it. But it was the third step: being there at exactly the right time -- and when the sky was clear -- that was the hardest. Five times over six years the photographer tried and found bad weather. Finally, just ten days ago, the weather was perfect, and a photographic dream was realized. Taken in PiemonteItaly, the cathedral in the foreground is the Basilica of Superga, the mountain in the middle is Monviso, and, well, you know which moon is in the background. Here, even though the setting Moon was captured in a crescent phase, the exposure was long enough for doubly reflected Earthlight, called the da Vinci glow, to illuminate the entire top of the Moon.
