It is very subtle. I expect you are good at picking out those kinds of variations if you are an astrophotography enthusiast. In the attachment to this reply, I ran the third image through the GIMP posterize filter, which exaggerates that effect by reducing the number of colors in an image, to demonstrate what jswinden is seeing. Please don't panic, this is not what it looks like in real life!
