Nicely lit, nicely composed, nicely photographed. I like it. Had to look up what it is, though! ('sporangium', not 'moss' )

A stack? Or enough DoF without stacking? What is the size of the sporangium? (Had to use that word now I know what it is )

Thanks for the nice comments, Steve.

Yes, it was a stack, of 14 x 1/2 degrees of focus ring rotation.
The head of the sporangium is about a mm. long, I actually forgot to take a scale rule shot, so that's just a rough dim. from life.
I don't think there would be enough DOF for a single shot, certainly not enough to capture the twisting of the stem.
Although I could capture the head alone with a single shot, it would involve increasing the f-stop & then you're into diffraction.
I can't help but believe I'm flirting with that all the time, to be honest, especially at these magnifications......
but I don't see the point of sailing really close to the wind with the number of shots in a stack, it being almost impossible to estimate the rate of overlap of DOF from shot to shot. Better to have too many than not enough!
