I wonder if it would work better if Luke only said.
“There it is”
?
Just a small thought. Perhaps that would establish it better as a hidden strange world nameless and unchartered in the Dagobah system?
Dagobah star system…
But Obi Wan called it Dagobah by name when he came to Luke on Hoth. The name is established. It would be rather difficult to change his dialogue, and even if it could, I feel Ady would be moving away from doing a superior special edition and ESB:R would start becoming a different beast altogether, along the lines of a new fanedit.
