Sorry I should have looked up a representative supercluster before I voiced my opinion as to a 3.5 billion light-year in distance upper limit. For as we read this Sloan Great Wall report we see a distance of 1 billion light years.
--- quoting from Wikipedia on distances of the Sloan Great Wall --- Its discovery was announced from Princeton University on October 20, 2003, by J. Richard Gott III, Mario Juri?, and their colleagues, based on data from the Sloan Digital Sky Survey. The wall measures 1.38 billion light years (1.30×1025 m) in length, which is approximately 1/60 of the diameter of the observable universe, and it is located approximately one billion light-years from Earth. --- end quote ---
So I am going to downsize my guess as to the upper limit of distance to see galaxies as being just 1 billion light years.
But another feature of current day astronomy is their horrible guess of the Sloan Great Wall being 1.38 billion light years in diameter. I cannot point to where their mistake is in thinking it is so vastly large in diameter. But I can point out the errors they made overall. That they thought redshift was Doppler when it all it is, is a curvature of Space redshift and that the Sloan Great Wall is actually very close to Earth compared to many other galaxies. For if you take Space to be a ellipsoid tear drop shape, and Earth on the axis of this ellipsoid and looking down the flank or side of the ellipsoid is the Sloan Great Wall and giving the reason for that immense curvature to make a large redshift. So that the Sloan Great Wall may actually be much closer than 1 billion light years and perhaps 300 million light years. And because we can see so much of the structure of the Sloan, hints to us that like approaching a city and starting to see all the structures, tells us we are closer than we think.
So let me revise my wild guess of 3.5 billion light years as the upper limit of seeing galaxies to that of a mere 1 billion light years and that most galaxies are in the 300 million light year range. And the length of the Sloan should also be downsized significantly.
