Like other new CMOS cameras being introduced into the astrophotography market, the ZWO ASI 294MM Pro seems to be a strange beast (but not in a bad way).The first thing to notice is that it has a “jump” in performance at Gain 120.

How much of this might apply to the OSC version, i.e., ASI294MC PRO ?

There is no corresponding bin1 mode in ASI294MC. The sensors are different, IMX294 in ASI294MC and IMX492 in ASI294MM. Not sure how much they are different besides CFA. The IMX294 is 'Quad Bayer' with similar 2.3um pixels grouped by 4 into larger pixels, then covered with CFA. Even if the sensor itself has similar bin1 mode, software would have hard time interpreting that funny Bayer pattern.
