I'd like to see a Sony data sheet that shows an absolute QE for their sensors. Every (Sony) data sheet I've seen to date has relative QE's....a useless figure IMHO.
As far as I know, Sony don't publish this data...hence I'd question (QHY's) claims of 50% QE in H-Alpha for *any* Bayer matrix sensor.
I'd however be very happy to be shown a suitable web link.....
