I’d expect that 0.33” is more than slight oversampling the vast majority of the time

The advantage of the mono sensor (if it is an advantage at all), is that if the 72 has some blue haloing going on, you can refocus with the blue filter to minimise it. The colour filters have UV/IR cut built-in.

Regarding the gain, unity (120?) once HCG is enabled is probably a good spot, although a little higher wouldn’t hurt.

FWIW, unity isn’t actually true unity on this camera...it is ~5e/ADU since the well depth is substantially higher than the ADC resolution by about 4x...the wells may be able to accomodate ~63k electrons, but the 14-bit ADC can’t express that full range. That’s a very similar situation to the 1600. FWIW2, there’s no magic or purity in unity
