It's not moire.

I see the bands you speak of. I can think of two possible causes - first is that you enhanced the brightness of this image significantly during post processing, causing posterization. Second is that you used a very low quality JPEG setting causing visible artifacts.

Yep, I think it's No.2, the "bands" are jpg compression artifacts. In other words, the jpg doesn't have enough colors to accurately display the gradients.

Images with such smooth tones need top quality jpgs. I would use a 16-bit tiff to print.

Lovely image btw!
