Are you using linked wavelets in Registax? If so you'll need to increase the 'de-noise' value by each layer. Another possible cause is the mirror misting up, I produced a similar looking image at Christmas when this happened. Or the focus could be a bit off, it's more difficult to nail with the barlow.

Another thing that will help is an RGB align, notice how there is a red tinge upper right and a blue one on the opposite side.

Good luck getting it resolved.
