The overall image was shot by rotating around the entrance pupil with an exposure of f/16 at 1 second. Magnification was about 2.4X.
The center was stitched from 2 focus stacked frames at about 2X with 80 individual images in each. These were shot at f/5.6 and 1/6 second. Average change in bellows draw was 0.212mm for 0.07mm slices.
p.s. Image size is 6890x5429 or 20"x23". The original composition was about 4 times larger, but wasn't very pleasing
