If there’s a “moment of national danger” happening under those circumstances, maybe it’s not resources that are the problem. Maybe leadership is the problem.

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.
