I'm showing averages across channels, which isn't normally an issue, except the Ra channels are very unbalanced. Very low red read noise is dragging the average down. If it were green I think it would be unchanged. And strangely blue EOS Ra is noisier than EOS R.

I was using an OLED TV for the test patterns. (for both the 60Da and Ra). Does that affect the analysis?

For my tests the spectral characteristics of the light source don't affect the results.

Is there something with the timing for read noise that Canon could somehow optimize for red Ha nebula at the expense of blue Reflection nebula?

Timing would be the same for all channels. They are scaled differently.
