(the spikes rotate in respect to the background because of the field rotator and that is virtually impossible to correct in post). Not sure if it is appreciated if I post the link here. Therefore a short summary.

WebThis is why larger telescopes have smaller Airy disks. It's similar to how a narrow slit makes a wider diffraction figure, whereas a wider slit makes a tighter figure. In the case of a telescope, the diffraction figure is the Airy disk - instead of having parallel diffraction zones, it's circular. A larger aperture makes a smaller Airy disk. 2.
