PRIMARY MIRROR INFLUENCE Primary mirrors in reflecting telescopes cause light waves to interact as they direct light to the secondary mirror. So, even if a telescope had no struts, it would still create a diffraction pattern. The shape of the primary mirror, in particular the number of edges it has, determines the mirror's diffraction pattern. Light waves interact with those edges to create perpendicular diffraction spikes.
