While 0.7 out of 1.2 is quite a high error range, I'll simply observe that
stars in the process of being MatrioshkaBrainIzed *will* be "underluminous"
in the visible spectrum. I suspect for an advanced technological
civilization, ~6 light years away is *not* that far if one wants to
observe a civilization making the singularity transition. (Going back
to my comments regarding the mass capacity for billions of lunar diameter
telescopes or their equivalent spread over an even larger area and used
for interferometric observations.)
