Quote:I think I have been holding onto the old view, and just translating it to Airy disk size. But I now think is correct is that we see more rings of the diffraction pattern for brighter stars, since everything is brighter, and that gives the appearance of greater diameter - yet the actual size of the disk and ring structure is the same size for all stars.
