Both artefacts give the impression of resolution, when viewed at small screen size, but even a half R'sed close inspection reveals the awful fake news  ....provided the image posted is actually displayed at a reasonable size in order to be able to do this of course 
The granular look seen in the low signal areas or the background, is a whole separate problem.

Yes Mike,
I know what you mean - I've seen it as well in high signal areas.
Just to illustrate the point -
I have made a sample picture from a bee shot that I did in January
and posted in the Terrestrial section here in Ice in Space:
http://www.iceinspace.com.au/forum/s...d.php?t=180548
I show below 3 cropped versions to have a full 100% size comparison.
the first is the original - not sharpened,
the 2nd shows the image at 2 pixel smart sharpening which is from memory
what I used for the photo I posted.
The 3rd is one that I have deliberately over-sharpened in Fitswork4
at 4 pixels deconvolution to show what happens as a demonstration only.
I believe it shows the sharpening worms and dots that you're talking about?
cheers
Allan
