A guy on an astromony club page posted the following meta data associated with the picture:
f/4, ISO 51,200, and 1/4 second, on a Nikon D5 with 22 mm focal length.
No Hasselblad anymore.
That meta data would work out to half (0.512 times) the light grasp of the Sunny f/16 rule, assuming the moon was 400,000 times less bright than the sun, and ignoring the two-loss way through the earth’s atmosphere. It also implies a field of view of 57 x 80 degrees in the camera.
0.512 times is one f/stop, going from f/4 to f/2.8.
Quarter second seems to match the slight motion blur of the lights. It’s the first NASA APOD that I have downloaded and saved. Very impressive. To me, anyway.
