Thanks! I played with the brushes and able to fix the Newton's rings (it takes some efforts to do it though)! Jake

Hello all, My wife and I went to Yellowknife in Canada to picture the northern light a few days ago. I borrowed my friend's Canon EOS 550D and the Sigma wide angle lens (10-20mm f/3.5 EX DC HSM). We were lucky enough to see the great natural phenomenon. However, somehow in the middle of the photos, there are "rings" appeared. I don't know the exact cause but I think it is related to the lens. I attached a few samples and hope this will help to explain. I am a newbie in photo editing and I wonder is there a simple way to batch remove the "rings", plus some manual work to fine tune the final images in Affinity photo? The photos were shot in JPG and RAW. Will be really grateful if there is a way to fix it :-) //bow Jake
