Great news!! My new toy arrives… now I need some time to set all, and it’s not simple!!!
It’s one of the new cameras from QHY (the QHY268M ) using the super hyped sensor Back Illuminated (BSI) Sony IMX571.
It’s a monochrome sensor with native 16-bit A/D and 3.76um pixels with a 75ke full welll and really low noise (1.1e- at high gain).
The diagonal is 28.3mm, could be could down 30º below ambient temperature and write 26 Megapixels images.
I am really excited but it’s a Pandora’s box: “Any source of great and unexpected troubles”
Update on April 30
