Product Description
The SBIG AO-X is a large aperture AO designed to be compatible with all large format SBIG cameras. It requires an off-axis guide camera behind the AO; typically the StarChaser SC-3 is used.
The AO-X is compatible with the Aluma AC4040 and Aluma AC2020 cameras, when used with a StarChaser SC-3.
AO-X is also compatible with older STX-16803, STXL-16200, STXL-11000, and STXL-6303 cameras. Guiding can be performed via a StarChaser SC-3, or through older guide systems including STX Guider, FW8G-STXL self-guided filter wheels, the built-in guide sensor on some STX cameras, or a Remote Guide Head with an off-axis guider behind the AO-X.
Note: When using with StarChaser with AO, you will need a StarChaser to AO-X/AO-8T Adapter Cable. The necessary adapter cable is included in our StarChaser SC-3 / AO-X Bundle.
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-X will clearly result in improved resolution under the right conditions.
