Improve observation data post processing. Lasers are used as artificial stars [1] to subtract atmospheric distortion, use stacking [2] to remove StarLink tracks. Those observations aren't being "ruined", they simply have some noise to remove.

Long term, we should be lifting observatories (both optical and RF) into orbit, Lagrange points, or the Moon. Observing from the ground sucks comparatively, and there's a lot of space out there.
