Dennis, that looks good but I have to agree that too much smoothing has been done. I actually bought Neat Image so that I could process 16-bit Tiffs and usually reduce the default smoothing to between 25 and 50% at all spatial frequencies and turn off sharpening completely. The combination of 100% smoothing and sharpening can result in really smooth images with enhanced detail that although smooth and sharp, end up looking plastic.
I can vouch for Steve's post regarding PixInsight, it's one of the most powerful image prcoessing applications out there, and I'm not just saying that because I'm on the development team
