Not to minimize the impact that large constellations *could* have on ground-based astronomy, but without more context, this isn't really "proof" of anything. A follow-up tweet[0] says "If you take the 2-hr video and stack the images, the astronomical wonders appear to get lost behind the web of satellite trails. 60s exposures, 4.4degX4.4deg", but was there some astronomical objective behind stacking 2 hours worth of frames, or was this just done to create a pretty/scary picture?
