With that though I'd have a 15mp BSI mono FF sensor with a QE peaking at near 90% and 7.52 micron pixels. Although it doesn't get the same SNR improvement with binning as a CCD it also doesn't have the high near noise which was the purpose of hardware binning anyway.



But the QHY600 with the IMX455 sensor is a beast.
The Quantum efficiency is amazing peaking at nearly 85%:

3.76um pixels and native 16-bit A/D.
sensor size of 36mm x 24mm
Low Read Noise 1.0e to 3.7e
Price US$5,000

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.
