The technique for ``roll deconvolution'' outlined here is very promising for future work with the HST even after the images have been ``fixed'' by the first servicing mission. It appears to provide good resolution down to the theoretical limit of the telescope aperture.
Its better to dither than hang tight. But your best bet is to roll with the punches.
