Not to beat a dead horse here, but did you actually take an image with your main camera yet? The last graph that you said was "best one but still not good" shows +- 1 arc second (assuming that your graph scale is set to arc seconds and not pixels, and assuming you have entered your focal length in phd2)

That would be quite acceptable to me on most nights.
