What may come around, assuming that low readout noise cameras become
generally available, is software that selects high quality short frames
and stacks them automatically. This is done already with planets, of
course, but doesn't work with dim objects. Unfortunately, as the size of
the field increases, the number of useable high resolution frames
decreases. It might take several hours to collect a few minutes worth of
data.
