AO-XThe AO-X is a large aperture AO designed to be compatible with all STX and STXL series cameras, including the STX-16803, STXL-16200, STXL-11000 and STXL-6303. The AO-X requies minimal backfocus while offering a large 3" aperture optical element, which is large enough to cover the KAF-16803 CCD sensor. The AO-X requires an off-axis guide camera behind the device. For STXL cameras, we recommend using the FW8G-STXL filter wheel. For STX cameras, the AO-X stacks on top of the FW7-STX and STX Guider. (Can also be used with FW5-STX.) The AO-X can also be used with a Remote Guide Head if you have a custom Off-Axis Guider setup. AO ResultsThe images below are actual star images showing the effect of image wander corrected at 1 Hz and 10 Hz:
1Hz Corrections 10Hz Corrections And the resulting size of the star image in a long exposure:
1Hz 10Hz 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:
The improvement in stellar profiles can also be seen at corrections above 1 Hz. First by looking at the non-AO guided image:
