Product Description
AO-8 Adaptive Optics is available with several different mounting plates and cables. The AO-8 works with the following hardware:
- STC series with StarChaser SC-2 (choose AO-8A)
- Aluma CCD series with SC-2 or FW8G-Aluma (choose AO-8A)
- STT series with SC-2 (choose AO-8A) or FW8G-STT (choose AO-8T)
- ST self-guided cameras (choose AO-8)
Note: When using with StarChaser SC-2 with AO, you will need a StarChaser to AO-X/AO-8T Adapter Cable.
AO Results
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:
1 Hz Corrections
10 Hz Corrections
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:
And comparing the non-AO guided image to the AO guided image there is again significant improvement in the FWHM of the star profile:
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.
