Wikipedia, The Free Encyclopedia, 22 Jan. “Diffraction spike.” Wikipedia, The Free Encyclopedia. Diffraction spikes are caused by the bending of light as it passes near the crossed metal support-arm system (spider) that holds our telescopes secondary. Nicely done calculation to reproduce that and figure it out so swiftly.” Twitter, 17 March 2022, Perrin, Marshall “Correct, it’s both the hexagonal outer perimeter (mostly) and also the segment gaps (which add higher frequency details). The spikes of the other two overlap with the spike of the gap, so are not actually visible.” Twitter, 17 March 2022, The horizontal spike is caused by the secondary support(vertical one). Those thick spikes are mostly caused by the gaps between segments. 管笑天 “I ran the actual NIR selfie through Maskulator. Diffraction spike caused by support rods When the primary mirror directs the incoming light rays onto a secondary mirror.

If your telescope has a larger primary mirror, you must be very well-versed with these patterns. This is why reflectors always have four struts supporting the secondary, not three. Diffraction spikes are a direct effect of telescopic observations. That’s just how diffraction works, 3 struts gives 6 spikes, 4 struts gives 4 spikes. Now that’s good optics! 😉 #UnfoldTheUniverse Curious about this image? Thread ⬇️” Twitter, 16 March 2022, There are 6 spikes, not four, because the Webb secondary assembly has three struts. The crosses, known as diffraction spikes, are caused by the lights path being disturbed slightly as it passes by the cross-shaped struts that support the. Shown to the left in this exposure of the bright star Antares, diffraction spikes are artifacts that show themselves on brighter stars in our images when the. NASA Webb Telescope “Small adjustments, major progress! Having completed 2 more mirror alignment steps, #NASAWebb’s optical performance will be able to meet or exceed its science goals. “Tweet Message.” Twitter, date posted, URL.
