Another excellent shot! (y)
I have a question: why do you make actually 70 shots? How do you calculate it?
105mm MC has closest distance 29cm. the flower is about 10cm and my table of DoF gives me 0,33cm by F11 by closest distance (29cm) on FX sensor. That would mean that for 10cm in focus I need ca. 30 shots. Unless I worry about diffraction and go with F8... but then it is 44 shots and still not 70. Unless the DoF must be more than 10cm?
How do you come to 70?

I typically go toward the lower end as far as increment, usually 2-3 in camera. Also, I normally leave plenty leeway in the foreground and background to prevent any strange artifacts. I have been focus stacking for years and mostly with the 200mm f/4 Nikon in manual focus and found for flowers 60-100 shots provide the best results. It also leaves minimal cleanup in Helicon or photoshop. Sometimes I might nix 15-25 frames before sending to Helicon but would rather have a few too many than not enough. Also most of the time I use a larger aperture such as f/5.6 which requires more shots. My process is more from experience than a scientific approach lol. Hope that helps
