Photo end result is excellent, however you did not tell the whole story. EXIF shows f=16 and S 1/15 sec. [right?]
You have a steady hand taking 1/15 sec photos, but would it not have been OK to use a higher speed as typically needed for those with vibrating hands. Since you are stacking, the moving part of the resulting photo would have been blurred and the fixed part sharp, which was your goal.
I was using photos I had on hand for my experiment. I was using IBIS and as I recall, a somewhat wide angle of view. Perhaps a higher shutter speed would work but certainly would have required more images to average.
