I took a series of images of lunar eclipse, through a thin and varying
cloud however. Then I processed them as I learned to do. Even with the
cloud veil, they still show the luminance gradients well, see the file

Next time we can mutually calibrate our instruments with such a hemisferic
luminance standard!
