Hmmm, so my 'expert' opinion
The first one looks pretty good in terms of detail and focus. The tones look good too. It just looks noisy which you can see in the dark areas. But
I really couldn't say how to fix it. Maybe one of the real experts knows?
The second one looks a bit soft on focus, but could be due to turbulance. I was sketching the moon last night and was amazed at how much the image expands and contracts under high mag.
The last one looks nice and sharp. A bit of processing artifact in the top left but that can be cropped. Although it does seem wider than the normal edge I get on lunar shots.
