Mind you I haven't tried it in autostakkert - could be a job for the weekend.

Thanks Andrew, I agree.

In my basic understanding and explanation, I think it is all about the ability to view the disk as a whole, and then be able to zoom to the native level of resolution as imaged at 2.5X. You have the best of both worlds. If I were to image the disk at prime focus (560mm) on a chip 1280x960 pixels, any attempt to zoom into the disk would pixelate on the details as there are too few pixels to represent the surface structures, remembering that the sun's disk spans 1800 arc secs.
