To Antoniseb, trust me I am not confusing the center of our milky was with the center of galaxies. I was pointing out that it would be difficult, impossible as far as I know, To look at a number of stars and say where the center of the milky way is. Mankind through all the ages didn't do it until telescopes came on line.
To Neowatcher, according to your math as I understand it; You could look at two stars and tell where the center of the milky way is? Two galaxies where Tipperary is?
