    I just downloaded CombineZM freeware
    and gave it a quick run after a glance at this tutorial:
    Oh, man, this is going to take some work to get good results. The first
    test was really awful! I guess the next step is Helicon focus, if I'm
    going to spend that much time figuring it out, it's worth a few bucks.
    ($20 to $300, 30 day trial)

    Computer is vista Intel duo 2.2ghz laptop with 3gb RAM, 12mp camera, an
    older version of PS CS and would probably work from jpegs made with
    Lightroom 2. I will likely upgrade to windows 7 soon, dunno if 64 bit is
    possible, probably need a motherboard upgrade which I won't likely do.

    Any comments welcome, sorry I don't have much to contribute yet. I do
    have a nice custom rig with bellows & easy stable fine adjustments; it
    takes about 10 turns to move 1mm. By a 'turn' I mean about 1/3 rotation
    on the knob, a comfortable increment. The fine adjustment is good for
    about 6mm depth plus a coarse adjustment of around 20mm in about 6
    turns. Magnification from around 1:1 to 9:1 with various cobbled
    together lenses.

    There's freeware that works much better and faster than helicon's crap. But
    I don't help snapshooting trolls and idiots.

    I did 12 frames at 9:1 with about 0.5mm movement and realized that was
    grossly inadequate. Then I did another 60-frame sequence and got an
    error. That was at about 1:1 and about 0.1mm increment.

    Here's one at 12:1 with 7 frames, which is not bad, maybe 0.2mm movements:

    Thanks, I'll give it a peek & report back.

    OK I tried your Zerene Stacker suggestion on the above set that
    CombineZM choked on and it was easy with a few accessible options:
    I did have to mask out the background using the furthest back slice. The
    program includes a cloning tool but I'm more comfortable in photoshop,
    there's also an auto mask contrast thing. 61 frames over 6mm is perhaps
    overkill but the result looks great. Actually I used quality 60
    irfanview jpeg copies to speed things up so jpeg artefacts are pretty
    bad. Still just testing.
    I see that it is a 30-day trial copy and costs $90 to $290 after.
    About the same as helicon. I guess I should try that trial version too.

    I like it so far. Nice documentation:
