That's an interesting observation Lee. This is just MaximDL picking the guide star only. So it must be picking the star that is can guide on or the brightest star. I too wonder if that would have a significant effect on guiding. I suspect not give the diameter of the star, but perhaps it does.

1x1 binning shows up even slight errors.

That image of Carina is a few days old Greg. That is while I was playing with the AOX. The guide graph is all I was demonstrating in my latest post.
The image taken with the AOX does have slightly elongated stars. It seems to be caused by the AOX reacquiring the star and then no delay being applied to the exposure despite asking for one in the options menu. I am planning on asking Cyanogen why this is being caused. I have delay at 10 seconds but when I do that the AOX part of the software freezes. Weird stuff.
