Webharpage • 2 yr. ago. Diffraction spikes are caused by the spider holding the secondary mirror. They're more prominent on brighter targets. The only way to remove them is to reduce exposure time, but for deep space astrophotography where this often isn't practical and you have very bright stars, people will resort to replacing the spider with ...

Explanation
WebApr 21, 2024 · Diffraction occurs for the same reason in reflecting telescopes as it does in refracting telescopes: it is passing through an aperture. There is no threshold aperture diameter for which you have diffraction. No matter how big the aperture, you will have diffraction. No matter the shape of the aperture, you will also have diffraction. WebMar 16, 2024 · "We now have achieved what's called 'diffraction limited alignment' of the telescope: The images are focused together as finely as the laws of physics allow," said Marshall Perrin who works on...
