I cringe at the meaningless and incongruous comparison of a
resolution figure with the width of a hair. Anyway, better
resolution and smaller size inevitably go at the cost of
sensitivity. I don't see these things being of any use in
astronomy, although they may be useful in setups where the
light intensity is plenty.
