In the centre of each photo concentric grey rings are visible. Any idea what causes this?</P><P>Prior and subsequent daytime and lowlight photos do not show the grey circles. I attach a sample here you can see the rings just below the main cloud.&nbsp;<span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="Aurora.jpg" style="width: 1200px;"><img src="https://community.sony.rs/t5/image/serverpage/image-id/503237i33915291252ACA10/image-size/large?v=v2&amp;px=999" role="button" title="Aurora.jpg" alt="Aurora.jpg" /></span></P> Sun, 25 Jan 2026 20:43:53 GMT glaopt1 2026-01-25T20:43:53Z https://community.sony.rs/t5/general-chat/concentric-rings-on-aurora-photos/m-p/3986423#M15602 <P>Hi</P><P>I took photos of the aurora - exposure about 20-30 secs - with a sony A7M3 and 28-105G.
