I think I spoke too soon regarding issues with the QHY5LII-M camera on a recent thread ... Using the nightly build from a day ago, I get errors that I think are related to subframes, which may be generating a problem with exposure time. PHD2 using indi driver for the QHY5LII-M had been working file until now. I've attached the log file - let me know if you want to see anything else.
