It should be noted that these views will require long time exposure photographs. The surface brightness of Andromeda and the Milky Way are both around 22 mag/arcsec2. As andromeda grows closer, the surface areas spreads out in our sky, so even as it gets closer it’s not really going to get brighter. https://en.m.wikipedia.org/wiki/Surface_brightness https://en.m.wikipedia.org/wiki/Surface_brightness
