Do they really think this is better than the original?

NIST claims that a newly developed de-blur technique has improved
the Tadpole Galaxy image from HST:

Look what APEX has done to the nucleus! All the've done is make
the noise more visible....

For the most part, the intent behind HST images isn't aesthetics.
Certainly, the sharpened image enhances many structural details.

All sharpening algorithms enhance noise. If you are studying a specific
object, you will normally apply a variety of filters to the image. Each
will help you tease out otherwise unseen details. Most of those images
that you are studying will be unaesthetic.
