The ones documented would have interest. But then as someone said about scientist over a hundred years ago would their instruments be as accurate as todays, or tomorrow's or next century.My point about measuring distance to a star that is many light years away is when you make the triangle (measure in June and December)the angle is only about 1 degree or if you were to draw it to scale it would look like a straight line.

Two straight lines of 100 light years long with a base of around 187 million miles.

That would be like two people standing at arms length looking at an object 10 miles away (this is an example not a scaled down proof), and triangulating the distance.

I can aim a rifle, iron sights, within one arc minute. With pistol it is about 3 arc minutes. Astronomers using iron sights can do as well on stars. With precision gears and some optical aid they can measure much finer. Still, 50 to 100 parsecs is considered adequately far for that technique with telescopic magnification, and one parsec, as for Alpha Cent, is iron sights accuracy. For greater distance they like to use absolute magnitude.
