I apologize if this is a dumb question, or if I am not remembering things correctly, but ... ... wasn't one of the earliert objects (a Cepheid?) Hubble detected as red-shifted located within the Andromeda Galaxy? If so, and since we're on a "collision course" with the Andromeda, why didn't Hubble see this as a blue-shift? As a follow on queston ... on a more local scale, aren't the objects detected seen with a mix of red and blue shifts, since cosmic expansion (or the cosmological redshift) isn't quite enough yet to overcome all doppler shifts from local relative velocities? Then at a larger scale, when it is, the majority of objects are seen as redshifted? Thanks!
