Best dissecting microscopes for botanical subjects?

Helicon focus fully automates the process and creates stunning photos, 
assuming you have a DSLR camera.
I did a presentation including some work done with Helicon Focus at the 
International Aroid Conference in Hanoi last December and got some botanists 
very excited. Also creates a 3d image of the subject.

I had heard about, though I don't know where to find more information on it, 
a camera + computer setup where the camera took a series of pictures with 
gradually changing focus settings, and the pictures were then combined by 
the computer choosing only the in-focus portions to create the composite. 
This would be extremely useful in creating substantial depth of field for 
close-ups, and macro photography generally. If anyone knows anything about 
this equipment, I'd be very interested.
