  We first present a consistent canonical formulation of the general
(non-marginal) Oppenheimer-Snyder model. The switching between comoving and
stationary observer is achieved by promoting coordinate transformations between
dust proper time and Schwarzschild-Killing time to canonical ones. This leads
to a multivalued Hamiltonian which is deparameterizable. We then discuss the
quantization of comoving and stationary observers by employing the method of
Affine Coherent State Quantization (ACSQ). We thereby demonstrate that under
certain conditions the quantum corrected trajectories can replace the classical
singularity by a bounce. We then show that both comoving and stationary
observers see this bouncing collapse behavior. We finally discuss a switching
between these classes of observers at the quantum level.
