I'm using a dummy battery hooked up to a 12V battery via a USB powered hub, maybe that's part of the issue? I don't recall having this issue on previous shoots but I'll have to look back. Maybe PixInsight's banding reduction filer would help tone it down. Might a 12V DC-to-DC In-line power conditioner help? Have you replaced your 7DMKii with anything?
