@Innerworld this is what our sky looks like after it was hijacked by tech billionaires.
Thanks fElon Musk. Way to ruin the fucking night sky.
why are the satellite trails segmented?
Speculation:
One way of doing astro time-lapses with digital cameras is to combine many short-ish exposures in post. Fast-moving objects (when I tried this, ships and planes) can show up as segmented trails, because they move significantly during the brief interval between exposures.
The fast moving nature also makes them trivial to filter out of the final image.
Essentially every stacking program have options to reject outlier pixels, such as the satellites. Hell even just averaging the pixels in an image stack without the outlier rejection would greatly diminish the streaks.
It looks like they stacked the images by taking the maximum pixel values; any other method should've produced much fainter or nonexistent trails. A good way to show just how many satellites there are, but not a realistic depiction of their effect on astrophotography.
got it, thanks.
