For reference, I'm referring to my ASI294MM camera. I had no idea the 66ke full well depth spec *only applies in Bin2*. The full well depth is only 14.4ke in Bin1. I've been imaging with a quarter of the dynamic range available to me.
I was always impressed with the performance of my ASI2600MC despite it being OSC. That's because its full well depth is 50ke by default.
