The big round glow could well be a light leak somewhere. Or amp glow perhaps, though I don't know that sensor. Perhaps could you post an image of one of the affected frames?

My lights are usually between 2 and 5 minutes. Flat frames are <1 sec.
This image shows what i'm talking about. It's been stacked in DSS and then moved to StarTools and developed. I flip both vertically and horizontally when capturing so the glow seems to be right side. Only happens when the image is stretched a fair bit.
