Too true....and amateur systems can only correct for tip/tilt up to about 30Hz at this time (but that's not bad!) and way better than can be achieved with any mount
Pro systems run around 1000Hz and perform wavefront corrections as well using deformable mirrors which are *very* expensive
The next big thing for amateurs? (Oh my god...a Ruddizm
)
My guess would be orthogonal transfer chips...CCD's that actively shift charge collection at the focal plane.
