Banding / artifacts in star trails with Sony A7R-III

Hi,

I've done my first star trails photoshoot, and I'm really puzzled by the result. It looked as if there is some kind of checkmark pattern in the merged photo. I've applied curves layer that increases the contrast, and it show some kind of two concentric banding that covers across the entire image. I'm making this out of TIFF files that I generated from Lightroom, and layering in Photoshop in a bundle of 10 photos of the same opacity.

Has anyone experienced a similar problem with their star trail photos?
