SX160IS--am I wasteing my time?

I have been playing with CHDK on my SX160IS with only minor success (simple HDR script works, shutter release works).  I was wanting to be able to do focus stacking with the lens set at maximum (16x) and the camera coupled to a second lens (thus yielding photomicrographs).  Has anybody perhaps tried this?  I don't want to spend weeks learning the scripting if someone knows it won't work!   Thanks in advance for any help/hints.

When you say "only minor success",  what is not working for you ?

I can't speak for the optics involved here but focus stacking with CHDK is quite possible.  There has been a lot of recent work making sure CHDK script can manually set focus and the SX160 result look good.

There is this :

and this :

if you are looking for reference material.

The SX160IS isn't currently straight forward to set manual focus by script, see this thread

Good point.   

Testing showed that this should work for the SX160IS :

the same way it works for the SX50hs.
