Hi Peter. Looks good for a single image capture with some surface detail as well as some spots. I agree focus is difficult. One way that seems to work for me is with your 400D at prime focus / select movie mode/ zoom in 5x or even 10x if it's not too jumpy and focus that way.
While it's in movie mode, record a movie clip at HD.
Then (a) convert your movie into AVI ( you can choose a 1min or so section depending how many frames you want.
or (b) create an image sequence of the desired clip length. I use VideoPad Video Editor.
Option b works well for me at the moment...i can't seem to use the correct codec that AVI Stack 2 or Registax requires
when using option (a)
So i put in the image sequence, last night i used 500 frames into AVI Stack 2 (free) and start the process. I followed this for help with it

Good luck with it, i am currently experimenting with this same type of processing.
There might even be some tutorials coming up soon as well as the ones that i have found in google searches
It might even be worth trying with your ED80 aswell
