....Dawes limit states that the hubble can only resolve at .049 arc seconds. So, no atmospheric turbulence to worry about, no adaptive software required. What this really means is that we can't resolve stars that are closer than .05 arc seconds to another star.
If the stars in Andromeda away from the galactic center were spaced 4 LY apart in the plane of the image, then that would take care of the .049 arc seconds I suppose. But then there would be a lot of 'layers' in that image due to the galactic thickness, which I'd think would turn those points of light into a smeary soup.
