I find furry parts usually dissolve into a hazy mush (in places) when stacked. I learnt to avoid overlapping areas with widely different focal depths (to stop that blurred halo effect on the further-away feature). And extra side-lighting often delineates fine edges better in a deep stack (e.g. hairs). But I did little different to my usual approach here and the hairs came out s-o-o-o well (IMO). Wish they would always come out this clear!
Done with 5x mitty, full frame, pmax stack, no retouching. Shift x,y and scaling turned on (as I always do for low-mag, full-depth stacks). Stacked every other frame with 50% reduction in pre-process (don't often do that). 170 frames used. Right edge cropped off to hide an unsightly ent pin.
As I said, it's a bit of a mystery why the hairs rendered so well in this one. But the moon is in it's waxing gibbous phase - perhaps that's why
