Monarch Caterpillar Windshield

The Monarch Butterfly egg produced a teeny caterpillar:

Each time it molts, it eats all of its skin except for the transparent cap over the first body segment:

If the rest of the caterpillar were behind the windshield, it’d be feet-upward with its “face” at the top.

The picture comes from a focus-stacked set of microscope images captured with VLC; I turned the positioner’s elevation knob the smallest possible amount between each of 16 images along the 1 mm (-ish) height of the capsule. This magic incantation applies more weight to high-contrast and high-entropy regions:

align_image_stack -C -a monarch vlcsnap-2017-08-09-18h4*
enfuse --contrast-weight=0.8 --entropy-weight=0.8 -o Monarch_Windshield.jpg monarch00*
# empty line to reveal underscores in previous line

That came out pretty well.
