I'm reasonably familiar with special relativity and its effect such as time desynchronization, but I'm having trouble understanding how these effects come into play when we also consider the time for light to reach us. I'll describe my problem using this image:
We will be observing 2 objects (the red vertical lines). There are also 2 observers: A, which is standing still and B which is moving towards the objects.
We should expect that B sees a time desync. If we look at the plane of simultaneity (black solid line) we see that the farther object is observed further in the future. However the actual photons reaching A and B (at the point they meet) are the same. How can B see 'further' in the future than A, but still receive the same photons?
To clarify I'm aware that B doesn't see the solid line, but I would expect B to see further into the future than A as special relativity predicts a time desync.
