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:
However, at a 5Hz correction rate, the faster jitter is reduced:
And at a 10 Hz correction rate, significant improvement is seen:
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.
