The AO-8A works with the STF and Aluma series cameras.

The AO-8A requires an off-axis guide camera behind the device.  For Aluma cameras this requires either a StarChaser SC-2, FW8G-Aluma filter wheel, or a Remote Guide Head used with a custom Off-Axis Guider.  All STF cameras are supported via the StarChaser SC-2 (except STF-402 due to different mounting interface).

 

Other data gathered by Brad Wallis of JPL (Brad Wallis and Benoit Schillings developed the prototype for the original AO-7) show the the effect of rapid corrections on poor seeing.  At 1 Hz the larger, slower component is reduced, but the amplitude of the jitter remains about the same:

ao_1hz

However, at a 5Hz correction rate, the faster jitter is reduced:

ao_5hz

And at a 10 Hz correction rate, significant improvement is seen:

ao_10hz

 

Telescope mounts cannot correct faster than about once per second.  The 10Hz rate of the AO will clearly result in improved resolution under the right conditions.
