The AO-8A is designed for the Aluma Camera Series.
The AO-8A requires an off-axis guide camera behind the device. We recommend using the FW8G-Aluma filter wheel. The AO-8A can also be used with a Remote Guide Head if you have a custom Off-Axis Guider.
The images below are actual star images showing the effect of image wander corrected at 1 Hz and 10 Hz:
1 Hz Corrections
10 Hz Corrections
And the resulting size of the star image in a long exposure:
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:
