You're getting closer to the truth, but it's not there yet. Breathe-exhale. You do not yet fully understand the genius of well-understood SR. When Stella reaches her aphelion, everyone agrees that her watch marks 9 years. With her powerful telescope, she observes that the earth's clock marks 3 years. The problem, between you and me, is that you THINK: "It takes time for the light to arrive" and I think "What is seen is seen live, the effects are real and reciprocal". You start from the a priori that the speed of light (value c) is something real, because it is physically measured. It goes without saying that the a priori is fierce. R.H.
