With your settings on my Ra (15", iso6400) I see of the order 20 hotpixels (some colored) if I switch off long exposure noise reduction (just checked) ... The same typically holds for my R5... Thats way one does dark frames or long exposure noise reduction.

This is interesting as Franz has sent me files to check and I found no bad pixels on his Ra (or R5).

If the pixels are at random locations they are simply expected noise.

If the pixels are at fixed locations then this might relate to an uneven build-up of dark current when my test is not designed to locate.
