Weird Spiral Patterns High ISO D850???
1

While editing D850 photos of the Milky Way in Lightroom Classic CC, I noticed some weird spiral patterns when (examples below) zooming in at 100%, The patterns get much more noticeable when I make edits in Photoshop (Levels/Curves). As I recall, I used the mechanical shutter, not the electronic. I opened the same file in View NX-i and Capture NX, and I am not seeing the pattern at all. It leaves me to believe it may have something to do with how LR is reading the file? Has anyone seen this before, and know what it could be?

ISO 6400

10 sec

14mm (14-24)

f/2.8

Nikon D850
