I recently bought a new camera 2600mc pro. I was using 294mm pro before. I had NINA 3.1 installed and everything was fine. When I connected the new camera, every frame was completely dark, even without noise. I updated the ASCOM driver and the frames were now normal but with the native NINA driver everything remained the same, version 1.35.0.0. Now I've installed the latest version of NINA 3.2 RC014 with camera version 1.39.0.0, and frames are now saving normally, just like with the ASCOM driver.
