The QHY version of that 4/3 chip has some firmware issue with it at the moment. I have a ticket open with QHY to hopefully aid in getting it resolved.

Yes, there is a mono version of the Sony IMX571 APS-C detector on the way. I read on CN today that QHY is trying to get theirs out by mid January. Both ZWO and QHY introduced a new 4/3” sensor mono camera with a Sony IMX492 sensor a couple of months ago.
