Having taken some very deep h-alpha images, I have to say I'm pushed to tell *any* difference between 7, then 10 hours of H-alpha data from the same 'scope.
I'd settle for 4 hours of data with superb seeing, over a slightly higher QE during any imaging session.
There are a vast number of award winning astroimages that have been taken with the KAF11002 hence I find this sort of QE difference to be a bit moot
