This could be the end of CCD but at that price I'll stick with my QHY9 KAF8300
which is already down in light level at the edge of the
18 x 13.5mm sensor due to only a 2" focuser on my 10" f4 Newt.
I would need to upgrade to a super expensive 3" focuser and coma corrector and OAG
to run a large sensor.
To people who already have the other hardware I mentioned -
they could just plonk a QHY600 straight on to their rig
with only the spacing to consider - so it would be tempting.

It certainly isn’t cheap compared to the KAF-8300 but it’s also 4x the surface area, has pretty much twice the QE and less than half the read noise. When you compare it against the KAF-16200 or the KAI-11002 it’s actually a bargain.
