Astronomical time lapses are fascinating and there should be more.

Astronomical objects that visibly change in human timescales are pretty rare. A naked-eye visible supernova remnant was one of the first clues that challenged the idea that the heavens were static, permanently set by God.

you are free to create your own as NASA observatories release their imagery free to the public as they were paid for with the public's money from taxes. the problem with creating timelapse videos would be if the platform viewed the same object at least annually to see the changes.

Part of the reason you don't see them more is because commercial satellite mega-constellations (like Starlink) work against long exposure times by literally clouding and brightening our view of space. (1)
