good morning everybody,
i'm facing a problem during calibration steps.
i try to explain. i have all need files:
100 bias frames
15 dark frames
15 flat frames
8 light frames
if if go through batch preprocessing script i get a good result, except i failed flat acquisition and the image is clearly over corrected.
if i try to go through manual process (calibration of all frames) i get totally false colors.
i noticed that i get good results if i do not consider bias frames in manual preprocessing for image calibration.
which could be the problem?
thank you very much
Rino
