Hello,
In one week, QHY will be at NEAF, a large astronomy function in the United States. At that time, they will likely unveil new cameras and software ideas. I will not be there myself, but, I definitely know this discussion will benefit from what is about to happen. I know for a fact, QHY would like to see INDI drivers develop for their cameras. I also know the language limitations are hampering documentation and development in general. For that, I will do everything possible to assist.
I, myself, can presently test the following cameras: QHY2(old), QHY8(old), QHY5, QHY5L-II mono, QHY7, QHY9C, and QHY11C. And while I can probably get any of the hardware things one would like to know, I am not a programmer by profession. I wrote the first QHYimager, from which, the current OSI project is structured on. But Giampiero is the author of that project, and, he has no interest in INDI.
With regard to users of the QHY5-II series cameras, one should be aware this might have problems with the newest Lin_guider release, and, possibly with KStars should these changes in timing be promulgated to KStars guiding routines. This particular camera family is very sensitive to usb timing and what will work on one CPU is not necessarily a solution for others to follow.
Best wishes,
Dan
