This is what the whole 800mm gets me out of the RF 200-800.
To the astonishment of people who have never tried to take a picture straight at the moon before, this is only a 1/800 sec exposure at ISO-100. The normal rules about nighttime sky photography don’t apply for the moon on a clear night, because it’s lit by direct sunlight.
Is that what was going on? I noticed a blood moon-eqsue effect the other night but I figured it was just due to it rising through wildfire smoke or whatever, as usual.
