    Rings in center of high ISO northern lights photo

    Rings in center of high ISO northern lights photo
    Took some northern lights photos at ISO 6400 with D610. They turned out great except for some faint rings at the very center. Any ideas why these are es, I can photoshop them out, but I would like to not have them in the first place, or at least know why they are there in the first place.

    thank you

    Canít really see them here but ISO 6400 may be a bit much for the D610

    Looks like Newtonian rings to me.

    I'm not sure what you're seeing either as I don't see any circles. Since you have such a bright light source in your image, it might have something to do with lens flare. That can happen when light bounces around inside your lens. The effect it creates can be different for every lens. Some lenses handle it better than others. With a few lenses, the light bouncing around causes haze to appear in the image.

    I see them, did you have a UV filter or other type of filter on the lens, perhaps condensation on the lens .If so that's probably the cause, those are newton rings. Light bouncing back and forth between the lens and a flat filter element usually causes those.

    I see them if I tilt my laptop screen just right. Dead center. I could not see it on my phone.

    Newton rings. I will have to take the UV filter off for the next outing. I have not even thought about the filter since installing it.
    I blew the photo up to 20 X 30. They are still faint but much more noticeable at that size.
    thank you

    Thank you for your help, Marilynne
    they are very faint, but blow it up as big as you can and look dead center.

    hi Don
    I am very curious about the ISO being too much for the camera because there are two settings even higher. Where can I go to learn more about this issue?
    Thank you
