hi Ray,

Interesting results, I have the older Orion Steadystar AO where the OAG prism can actually be tilted to point to a different area in the FOV, would this help at all if tilted to point toward the centre?

Secondly, do you think using the lodestar in 2x2 binning had any effect on your results? the lodestar has fairly large pixels at 8.2micron. when you bin, don't you lower the resolution of the guiding component and would this affect centroid calculations especially if it is a bright star?

I had a brief chance to test the AO on my 10inchF4 with the stf8300 and it showed very promising results, this was with an NEQ6pro, and not very windy conditions. I normally use an OAG.
did you do any tests with 1x1 bin of the lodestar?

I got a lodestar X2 and had no issues with getting a guidestar at 100ms from a very LP backyard.
cloudy as hell, but I'll post some results as well when it clears up.

Looks like the benefits are more evident in a system with a higher resolution, typically less than 0.7 arcsec/pixel.
