We know that an observer at infinity cannot see a star forming into a black hole as the matter will take progressively longer and longer time to compress (from this observer's point of view).
Is there an observer, outside of the Schwarzschild radius, who is able to observe this taking place in a finite amount of time?
PS: I am aware of this question Can black holes form in a finite amount of time? I am not asking the same thing, as the answer there was given in terms of proper time. I am interested purely in real observers, but not necessarily sitting at infinity, the observer can be arbitrarily close to the Schwarzschild radius.
