> 547 AU For comparison Voyager-1 is now at a distance of 40 AU only.

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.

Is Voyager-1 still accelerating?

Nope, both are slowly decelerating as they leave the solar system: https://upload.wikimedia.org/wikipedia/commons/0/0c/Voyager_...

Is that number correct? Why not just launch at those starts at that point?

For comparison, the nearest star to us is 268,770 AU away, or around 491 times further away. It would take quite a bit longer to get there!

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.
