Thanks, Ken.
Nothing determines the number so shots that is used and I probably over
sample most of the time. I actually just stacked every other shot and
the result is virtually identical at web size. Looking at the actual
pixel size I can see a few areas where there is less detail. The double
images of some of the hairs at the very top of the moth are actually
reduced significantly using the 55 images.
For this kind of shot (working indoors) I use focusing rails and work
from front to back. (Outdoors I change the focusing on the lens.) I
start when the first detail shows up in live view (focus peaking
enabled) and try to move the camera forward as slowly as possible. I
watch the live view to see that the frames overlap, but it is really
more of an exercise in trying to be as consistent as possible. When I
first tried this I spaced the shots too far apart and that resulted in
alternating sharp / less sharp bands through the image. Sometimes I will
really miss and get a band that is out of focus running through the
final image. So I try to move the camera as little as humanly possible
and reduce the number of images to be combined later if need be. The
stacking software seems to be able to handle oversampling without major
issues, but at times I will drop down to every other or even every third
or fourth shot.
Like most of my setups I use a pretty improvised arrangement.

Wonderful image Mark.
What determines the need for 110 images?
What would it look like if you only took , say 55?

Thanks Frank. The moth was dead and mounted on a pin, so keeping it
still was not much of a problem. The lens was at f4.5 so the DOF was
very shallow, which is why it took 110 images to cover the subject.

Incredible photo!
110 images? How did you get him to stay still that long? Or do you just shoot
until he moves and then use however many you've taken?
Cheers,

A macro of a moth - probably a gypsy moth:

K3, DFA macro reverse mounted on extension tubes, dual flash setup (one
above, one below), 110 images focus stacked.
That old War song " Gypsy Man:- has been going through my head all
day!
Comment welcome.
