John, what are your settings, binning, exp length, filter, data points, star size, smart focus?
Have you used a digital vernier and physically measured the distance 1000 steps moves your focuser? This is very important.
What scope are you using?
The biggest problem I see straight up is that there are not enough stars in your screen shot and it is taken in twilight or the exposure is not long enough. The stars also do not look very round, are you using a flattener and if so, is the distance correct? This will affect focus very much.
