Ok, so I understand that for you it's a normal behaviour of the electronic noise, that's right? I agree with you that by stacking more frames, the phenomenom will desappear. I yet try that and it's ok.
One another question please :
I did a first master dark at the beginning of 2021 (30 frames). The standard deviation was 14,088 (16 bits).
Now I did new master black this year (end of 2022) with 76 frames. The new standard deviation is now 33,963 (16 bits). The masters were done in the same conditions (sensor at -10°C, in the same fridge in dark environment,....).
However, I notice a significant increase of the standard deviation (almost x2) between the 2 masterdarks. It seems that the camera supported a degradation of its performances. And i guess that this increase is due to the increase of the electronic noise (seen on the bias frames as I shew to you)
I joined the 2 masterdark for you to compare.
Is this evolution of the camera be normal after almost 2 years (I precise that the conclusion is the same in bin1 and bin2)?
