Quote:Ron, in theory the AO8 can update at 5Hz, so spikes should be a piece of cake. Now whether your guide camera can see decent stars at 0.2 second exposures.. is a whole different ball of wax.AO has pretty much the same challenges as OAG (needs a very sensitive guider) with the additional requirement that you need shorter exposures.Or you can use 1-2 second exposures like the rest of the world, and just use it to smooth out your mount's hiccups. In that case you will not be compensating for the seeing anymore which is supposedly what tip-tilt AO is really all about.
