Cheers Glen. He's plotted the relative QE, which is definitely useful info, but it's still not absolute QE.

My 674 has a peak absolute QE of 77% (from memory), but it's much flatter at the peak, so the shape of the relative QE tells me that I'll be losing out in red and blue, but I still don't know by how much because it doesn't tell me that the peak absolute QE of the 1600's sensor is X%.

It's estimated to be about 60%, but last I looked ZWO still didn't know exactly what it was.
