Mmm, that's an easy one: I can assure you constellations and nebulae are not as fast as peregrines.What is different about holding it up to the night sky and holding it up for Peregrines? I am usually seated when observing raptors or from a hide.
When seating on a reclining chair stargazing, there are many times where binoculars don't move at all, or move very little; the crucial bit is that there's no need for rush to follow any object. Recent example: just 4 hours ago I've been watching a couple of peregrines chasing each other and playing with really fast movements and moving swiftly across the sky. To follow the scene with your binoculars you had to be concentrated follow the scene (at some point, turning my neck and my torso where not enough to follow the course of the flight). Had I been seating, I would have simply missed the action.
