IVO,
You need to read the document I attached to the last message...
I take into account the f ratio and the camera pixel size in the calculations...
The enlarged saturated star images appear to exceed the diameter of the Airy rings..

Re Hubble - this would then infer that the brightest star image recorded will always been no larger than the extended Airy disk...is that really the case???
