It was a very dark eclipse, which posed a challenge to image as the Moon was so dark.
500 mm f/4 L IS at f/4, ISO 1600, 3 exposures of 0.4 seconds each, stacked in photoshop with 33 % opacity (the stack reduced noise). Then sharpened with Richardson-Lucy image deconvolution (5x5 box, 8 iterations). The 3 exposures were needed because one longer exposure would have been blurred by rotation of the Earth. Note the many stars in the background.
