Uneven noise reduction

Recently I made some comments regarding how layer masking and selective noise reduction can impart a somewhat obvious processed look to an image, well todays APOD is a classic example of this IMO. While this is a wonderful galaxy and indeed overall a great image showing lots of interesting bits, the uneven application of the noise reduction and sharpening is obvious to me..?

See how the centre is obviously sharper than the perifery, and the outer arms and sky have been overly smoothed in comparison? It looks like we are looking through a slightly steamed up window that has been cleared only in the middle.

Again I am not bagging the image as a whole (it is a great image allround) just some harmless observations regarding one aspect.
