I'm not arguing the Physics, it's pretty cut and dry, but you can't ignore the seeing component of any imaging session either (I suspect this is difficult to quantify).
While they are not ABG, the KAF3200 has had one of the highest QE's bar some pretty expensive back-illuminated chips, for around a decade now...maybe more
..... yet, assuming imaging is the goal, there do not seem to be many world beating KAF3200 based images on the web.
Begging the question: does the theory matter that much given the practical applications of many astro-imagers?
