Hi Ricardo,
Yes, adding 11 mm space under the objective lens for the piezo will
affect the image on your 160 mm (171 mm) tube length microscope. If
you are only interested in one plane, no need for the piezo. If you
have not purchased the piezo, an external focus motor could be fitted
to the focus knob if/when you do decide to acquire Z-series.
Yes, a high NA water immersion lens would be nice, but if you could
use mounting medium that matches your immersion oil's refractive
index (i.e. 1.515, same as glass), you would be fine. Of course your
goal is to image live cells. You could boost the R.I. of your live
cell culture medium using BSA, etc. to get at least close to index
matching. Let us know if it makes a significant difference! Since
your cells are probably within a couple of micrometers of the
coverglass, even standard aqueous vs immersion oil refractive index
difference will not be a killer - after all, plenty of researchers
have published live cell microscopy with oil immersion lenses.
2D deconvolution is part of Fovea Pro 4.0, a set of Photoshop
plugins. See the bottom of
http://www.reindeergraphics.com/index.php?option=com_content&task=view&id=206&Itemid=152
for example (astronomy). You can download an 3-week, fully
functional, version of Fovea from the company at

They also have a separate plugin, Focus Extender 1.0, that may be of
use with Z-series

Best wishes.
Sincerely,
