Hi Chuck,
Have seen some threads on pnet  that the software automagically can 
merge the images with either refocus or moving the stage.  The Helicon 
software is reportedly easier but may not be worth the price of 
admission.  With a very complex subject there may be too much ambiguity 
as to what should be in focus and the software will surrender and make 
a mess.
Perhaps that's it--perhaps not.  I like Moose's analysis too--worthy of 
a post from the long silent but missed Dr Focus.
Here are some tips from a link I posted before---check his procedures 
and skip the comparison stuff unless interested.

Also form the help page---you may have read this but just in case:

Seems to work OK with autofocus bracket with g9.

Prefer T-S for OM  but alas still groping for answers.  May consider 
one of these on front of the autotube with a custom stop down adapter 
---perhaps another cacamami idea.  Stacking is worthless in wind or 
chasing critters.

Perhaps you could inquire as to what Dr. Focus thinks?

Mebbe should listen to Walt who said if its windy find something else 
to do.

Moose's observation that moving the camera has a lesser effect on
magnification was an interesting and probably quite useful point.  On
the more general subject of changing magnification here is how I
responded this morning to the same question posed by Jim Brokaw on the
Kiron user's list on Yahoo.
