Looks good Frank. In my experience you won't lose details with a slight deconcolution but you will in PS with sharpening if you're not careful whethere you use highpass filter or another method. Also the dust and scratches noise filter has to be used with some kind of threshold. In your pic I'd say a minmum of 20 or you'll kill details quick as well as all those white specs. When you apply filters it's good to create a black mask on the same layer and only paint white the area you want to be corrected so the whole image doesn't get modified. Finally when saving a 16bits scaled TIFF from a raw file in CCDStack, make sure you lower the background slider right back or you'll black clip your picture histogram, which is the case in your shot.
