Now that I am actually using an automated stacking rail (WeMacro), its tempting to make the step size smaller than it should be. We all know the issues of too large a step size, which leads to banding of unfocused areas. Is there a down side to making step sizes much too small (i.e. 40 micron should be fine based on mag and aperture, but use 5 micron instead)? Yes, this results in much longer computation time (and longer sitting in the dark contemplating the universe while waiting for the stack to finish).

There'll be a little more noise accumulation with PMax. Other than that, only the issues that you've mentioned.

Particularly difficult subjects may benefit from the reduced "squirming" (apparent lateral movement of subject features) that results from smaller focus steps.
