My (limited) experience with "super-resolution" is that it doesn't work
nearly as well as advertised. But of course, YMMV. I suspect a lot has to
do with how much control you have over the camera... If
they used it on Hubble or something, maybe it works well when they can
control things so closely, but even with just handheld digital cameras it
doesn't seem to produce more than a minimal gain.
