WebNov 16, 2024 · Yes, the artifacts are caused by the characteristics of the telescope's optics. The wavelength of light is also a factor, so the diffraction artifacts will manifest differently for different colors. And the way the data is processed also impacts how easily the diffraction artifacts are noticeable. WebMay 27, 2024 · There was a thread on the PI forum where somebody asked or a solution to eliminate spike artefacts on a alt-az telescope. (the spikes rotate in respect to the background because of the field rotator and that is virtually impossible to correct in post). Not sure if it is appreciated if I post the link here. Therefore a short summary.
