Hubble Optical System

Hubble Optical System

No optical system is perfect, and all telescopes with a circular aperture — or opening — will impose a pattern called an “Airy disk.” Any support structure that impedes on that circular aperture will add features like “rays.” Hubble has a secondary mirror with several support struts that cause this effect. With these imperfections you are actually getting a glimpse of how the Hubble Telescope itself is set up!
