Hello, I have a 1600mc cooled gen 1. I am trying to figure out the correct exposure setting for BIAS frames. I had tried doing 0.000032 exp with lens covered at temp set of -20C. I get the following image:


It seems to be way too bright for the correct Bias frame. I tried the camera indoors with the sensor covered with a cap and same results. What is the correct exposure setting for bias frames?
