E.g., this is the secondary image which has an exposure of 0.1sec. It is about 60sec after first image
was captured.
Don't worry about it. To avoid this. You can use a longer exposure time to do bias frame. For example:
0.3sec. There is no such black banding even you wait a long time and then capture. Please look at the
following pictures. We wait for one minute then do the secondary capture and it is uniform and has no
such banding.
E.g., this is the secondary image which has an exposure of 0.3sec. It is about 60sec after first image
captured. It doesn’t show any dark banding here. And we have tested for more longer like the
10minutes and still get the same result.
