When I take photos of the night sky, I get banding in the upper portion of the image. Neither increasing the ISO or changing lenses has helped. I would appreciate any help in this matter.

I am using a 27" iMac and a 27" second monitor and do not see any banding. Could you try to indicate where you are seeing it.
Thanks

Brian

If you lighten the picture you can easily see multiple bands, similar to a malfunctioning printer, this may suggest a read/write problem. If you use your second card as backup try loading the pics from that. You should use a different card to take more night shots in slot one to make sure it's functioning right. It could also be your card reader so try a different reader or download from the camera.

Thanks, I hadn't considered that but I will do some testing along the lines you suggest.

Dan, very good captures, but it is not banding, your first shot looks like a meteor, the third is an airplane and a meteor, I see no banding at all.

You didn't mention your camera make. Mirrorless?

Yes, definitely some untoward mostly horizontal lines in the images. In my experience the most common source of banding is compression when creating JPGs.

However a few years ago there were lots of discussions about specific camera models having slight banding issues in underexposed areas of the frame. This is not something you hear much about lately. Do a bit of research (ie: google banding & your camera model) and see what comes up.

I doubt it has to do with memory card issues since you do have stars showing up inside some of the bands.

Canon 5D mark IV, 24-105L or 16=35L. Either lens produces banding.
