When an accelerating astronaut is in very close orbit around a stationary observer the astronaut will see the observer's clock run fast. From this fact, I conclude the astronaut will see any light sent from the observer as blue-shifted. From the observer's view, everything is reversed i.e. the accelerating astronaut's clock is seen to run slow, and light from the astronaut is seen as red-shifted. Does anyone agree? I can't find any answers in textbooks.
