1. WeMacro Focus Rail
Canon MP-E 65mm - Canon 80D - Yonguno YN24EX - f5.6 - 193 micron units - 21 stack
The WeMacro Focus Rail offers the finest degree of control. The lowest increment can be as low as 1 micron. Although this degree of control may be needed for magnifications of x10+ - for insects at 5x - 62 microns is ample. WeMacro provides a very useful DOF Estimates For Macro Chart. Using this method one sets the depth of field step size based on aperture and magnification. I just looked it up on the DOF Estimate for Macro Chart. For example, on an APS-C sensor using f5.6 at 2x magnification 193 micron step sizes are recommended.
Pros: Offers the greatest degree of control and maximum magnification - an incredible 1 micron
Cons: Heavy - great for studio but not to so practical for field stacking
2. Novaflex Castel Q Focus Rail
Olympus Zuiko 60mm - Olympus STF-8 - f5.6 - quarter mm increments - 16 stack
There is always the good old fashioned way of manually stacking using a focus rail. Although much slower than using an automated method it does provide the satisfaction of being able to see the focus with each turn of the focus knob. With care and attention manual focus stacking can be suitable for maximum magnifications of 5x.
Pros: Area of focus can be clearly seen on-the-fly and with each turn of the focus knob.
Cons: Slow - by the time the stack is completed there’s a good chance the subject will have lost patience and moved
3. Olympus E-M1 in Camera Stacking — Olympus Zuiko 60mm - Raynox dcr-250 - Olympus STF-8 f.5.6 - Differential 8 - 8 stack
By far the quickest method and great for taking stacks in the filed. The camera generates 8 jgs and from these a final RAW composite is made. Alternatively one can bracket up to 99 images and have these imported into stacking software, such as Zerene Stacker. The main drawback of this method is that you have to estimate the focus point by setting a ‘differential’ between 1 - 10. 1 represents the smallest of increments and 10 the largest.
4. Olympus E-M1 in Camera Stacking — Raynox dcr-250 - Olympus Zuiko 60mm - Olympus STF-8 f.5.6 - Differential 2 - 8 stack
As can be seen, a diff of 8 provides substantially more depth of field than a diff of 2 (where only the mouth parts of the dragonfly exuviae are clearly in focus
Pros: The lightest and quickest method of all. Great for stacking in the field.
Olympus E-M1 with Olympus Zuiko 60mm lens and STF-8 twin flash weigh just under 1 kilo. Compare this to my Canon 5D and Yonguno YN24EX on Canon Speedlite Bracket SB-E2 weighing in at a whacking 3 and a half kilos!
Cons: The amount of focus increments needs to be approximated from a differential of 1 - 10. One can’t set the focus starting and ending points as with the WeMacro Focus Rail nor see what’s in and out of focus - as with manual stacking.

A series of 27 sunrise photos stacked together using StarStaX. There is a little bit of blur - must have bumped the tripod during the series!
Juicy & delicious watermelon, all eaten, nothing was left but the skins, so I thought I'd
stack them!

I got these glass boxes at the Container Store which stack up. I thought it would be cool for the each box to recharge the batteries of the box underneath it. It's like recycling light!

Chimney work — part of a renovation project converting an old factory building into condos and mixed business space at La Crosse, Wisconsin.
A crew from Dogsthorpe was called to a stack fire at a farm in Middle Road, Newborough.
Approximately 10 tonnes of baled straw was well alight and had spread to wooden pallets and trees.
Firefighters used hose reels and jets to contain and control the fire and a farmer with a teleporter assisted by removing wooden pallets.
At 9am the incident was handed back to the farmer and fire crews will return to inspect the stack.
The crew returned to station by 9.15am.
The cause of the fire was deliberate.
