That is incorrect. It's approximately at 150 AU[0]. For reference, that's about three times the distance of Pluto at aphelion. 547 AU is about 11 times the distance of Pluto at perihelion.
i guess i was thinking more about the complexity of arranging a constellation of telescopes around sol versus just sending one much closer to a target star.
