Did you catch that the object as viewed from earth is 52 micro-arc-seconds in diameter? That's some resolution.

If they can do 52 microseconds why are our total stations only good to 1 second?

Because of the size of their instrument. They are working with radio waves, not light, and combine signals from stations spanning the earth.

THat is pretty cool, thanks for the heads up that we can observe blackholes directly.    Time to go watch Interstellar again
