A month ago Adrían and I went to the French Pyrenees in search of snow as there was very little in Spain.
When we arrived at the refuge area a dense fog covered the peaks but during the blue hour it disappeared and never came back.
During the night when I took my Sony A7 astromodified I realized that I had left it on and it was without battery (if you have activated the infrared remote control does not turn off automatically), I thought about charging it with a powerbank but by chance the cable did not work.
So finally I had to shoot with my Sony A7riii and stack it and this was the result
Sky: 7x 180s f/3.2 ISO 800 20mm
Earth: (blue hour) 1/3s f11 ISO 200 12mm
