Brian,
What is your image scale (arcsec/px)??
With the wind, apart from the bloated stars, the bigger issue for me at my image scale (1.6 arcsec/px)? is the occasional gusts that will cause a big jump and I end up with pointy projections from my stars. If it isn't too many frames, I end up using Median combination in PixInsight which does a good job of rejecting them and still gives me a good integrated frame. I think your scale is much smaller than mine from the size of the nebula in relation to the overall frame.
