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. WebThe telescope forms object's image by imaging each and every of these point sources in its focal plane.
