Personally I prefer the one above: it looks more natural. The second one seems to have some halo due to sharpening on medium frequencies.
In any case, great images full of details.
to the left you can sense the circular outline of the large crater Schiapparelli. A good satisfaction!

Thank you! Motofoto I don't know what marks you mean:) Maybe I could make it slightly brighter. :) Could you be more specific?

I try to explain with this image:
1) The first on the left is your image second Image
2) The one in the middle has indicated a couple of lines that seem due to a very contrast mask Intense, more than a real feature on the planet's surface. The form, in fact, resumes the area contraright. The round one seems a posterization or an accentuation by contrast mask of the edge of the planet
3) The third is a speditive test of increase of sharpness, but the formation of those halos.
I do not know if it is clearer what I wanted to show you, especially having the first image that instead is very beautiful from a tonal point of view and without accentuations of "digital" sharpness. For that I have defined it natural (and very beautiful).

Another thing that disproves the fact that they are artifacts is the fact that the structures that you have highlighted are present in the filming of two different evenings elaborated in different ways and this point by two different authors. What I change is the seeing and the subscriptions of frames added up.

In my opinion, the structures that you mean could emit particularly in the IR for this are very visible. If I had done an RGB my picture surely you would have been more familiar:)
I think my and regular because between seeing, height of the planet and Apertira of the telescope I could not solve that structure well. Maybe in other conditions...;)
"When I see some dark and regular granularity and forms parallel to the areas contrasty I am instinctively thinking of a digital effect."
me, too... but I would never publish it if there were artifacts.

This is an interesting hypothesis.

you're right. I did not mean artifacts as fictitious elements, but more evidence of some forms than could be expected, especially in relation to the first image.
Given the quality of the results with Mars, Jupiter and other astronomical subjects, I had no doubt about your care: You have a beautiful gallery.

Thank you. Pity that on Juza nn you can upload photos with less than 1000 pixels per side... otherwise I would have photos ?
