Self-made CCD, similar to QHY8 Pro, details are in my signature.
Any thoughts.
Is there a better way to measure the dark current?
Thanks in advance

Yes that definitely seems odd. Can you look at the images for say -10deg C compared with the images for +5 deg C. Even post the images for comparison in this thread. On viewing - Do the -10 deg C images really suggest that they have a 10 times greater dark current (higher number and/or intensity of energised pixels)
