Point taken. So where do we draw the line? Flux hitting the sensor? or somewhere before that?

With a non filtered mono sensor how do we proceed?

Do we drop a ND filter in place so the single shot still looks good?

What about using a H-Alpha filter? ( trust me, this is not pretty for the CMOS).

Fair? What has fairness got to do with the sensitivity of a camera?

So many questions

But DSLR has 1/3 number of sensors for each colour. So the sensor gets 300 photons for the whole frame... this is 1/3 sensitivity compared with CCD mono.
Not fair comparison,
