Wind? That's the big one ....to which I'd like to add "astronomers with
big feet" as another problem.

One night I started getting trailed exposures and of course thought "What
now??!!" I looked over at my ST-9 on the back of the 20RC and realised that
the cable had gotten tangled around the 20 lb ladder and the moving scope
had lifted it right up off the floor! Try hi rez imaging with 20 lbs
dangling from your camera!
