Hi Barry,

I had a look at the SBIG AOG products, but that basically adjusts a tip/tilt mirror by very minute amounts upto 10 times a second to ensure that the guide star is centred on the chosen pixel. this primarily would correct mount periodic errors, wind deflections without adjusting RA directly.

but this is different from the AO on keck and LBT telescopes where the primary mirror and secondary mirror respectively are deformed to correct a distorted light wavefront so the final wavefront is in phase.

But I don't know how the laser AOG for the Keck works.

the AO on the LBT telescopes were the most impressive.

there was a TV program called Engineering connections with Richard hammond and how "Theremin" sensors were used on the LBT to align the mirror by extremely minute amounts so the hexagonal mirrors formed a perfect parabolic surface.

Love the video of the sun with and without adaptive optics.
