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. WebJul 21, 2006 · A single exposure records the spectra of all stars in the field of view. However, just as when using the telescope for astrophotography, exposure durations are limited by skyglow. These spectra were formed by projecting the image of a point and line of light through a Rainbow Optics diffraction grating.
