I have a narrowband dataset. After calibration and registration, all the individual frames are scaled to about 0.0-1.0. After ImageIntegration, the H-alpha and O-III average are also scaled about 0.0-1.0, but the S-II average scales to about 0.0-0.5. Why would ImageIntegration produce a different scale for the S-II? I have been using PixInsight for quite a while and this is the first time I have noticed this, although possibly it has happened before without realizing it. Any explanation and insight would be appreciated.
