Re: More on A.pellucida



Kevin, yes, I might have been too sharp in this discussion, might
refllect my state of mind these months.
Anyway, like for like, a 40x BF or in DF shouldn't suffer in
resolution. I achieved DF with a 70x objective with the full aperture
of 1.23 by relatively simple means (a patched aplanatic 1.4 condenser).
The view in DF is *very* detailed, see my yahoo photo album for an
example. DF is just not very practical for most specimen, especially
not in high NA. And, I agree with Gregor, even for diatoms I prefer COL
over DF.
