I am getting tight, regular banding across the entire image with my new 1600MM. Settings are unity gain 139 and offset 50. Integrating with calibration frames does not remove it. Can anyone give me suggestions on how to resolve? Thanks!

You can try calibration the banding by flats, dark flats, and bias.
