WebSep 13, 2024 · Diffraction spikes are typically produced in telescopes which use a secondary mirror held in front of the main mirror; it’s the secondary supports that create them. The JWST has a secondary mirror held in front of the main segmented mirror. There are three supports, one vertical and two angled at 150º to the vertical. 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.

WebNov 16, 2024 · Yes, the artifacts are caused by the characteristics of the telescope's optics. The wavelength of light is also a factor, so the diffraction artifacts will manifest differently for different colors. And the way the data is processed also impacts how easily the diffraction artifacts are noticeable. WebThe telescope forms object's image by imaging each and every of these point sources in its focal plane. The point-image itself is created by wave interference around focal point, due …
