Of course it can! BF microprobe - the best thing for all metals, because of good diffraction contrast. Even relatively good high-res STEM in nanoProbe mode could be realized without probe corrector. Just make main alignment: condenser aperture, condenser astigmatism and comma (by seeing ronchigramm) - and you will be pleasantly surprised!

Thank you for this really interesting and summarizing lecture!
Thank you :)
Very densely packed information, thank you!
Hi Nicholas...
Can STEM imaging be useful without probe corrector?
Yes, good for some non-hr imaging. STEM-BF dislocation image of some material could be way better than TEM-BF ones.
