Explanation 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.

WebMay 27, 2024 · There was a thread on the PI forum where somebody asked or a solution to eliminate spike artefacts on a alt-az telescope.
