I don't think focus stacking is implemented in PTStitcherNG, which
doesn't use pano12. As Rik (who implemented it in pano12) wrote, this
was more of an experiment than a real option. Better to use enfuse or
tufuse for that purpose.

Using the focus ring isn't recommended, since it changes magnification.
You would need to align the images regarding their Field of View. Moving
the camera provides the same magnification for each image.
