Rafael, that last image is one superb moon!!! That's the kind of view I have seen through my reflector telescope, now gathering dust in the garage. The best day to get crater details is about 2-3 days before or after full moon. Your image is inspiring me to try and stay awake long enough on perhaps Tuesday to get the 500 outside, this time with the TC16A or TC301.
Thank you Samy, allow me to share the techie side of getting that shot, I piled up the converters, one TC300, one TC 201 and one TC 14. The image is not cropped top to bottom. The quality of the lens is much lowered, but still better than 15 miles of atmosphere looking straight up or 100+ early in the rise/set. I closed the lens to f8 to get reasonable performance. Set the left top dial to mirror up,and exposure delay menu to three seconds, I use a cable release and set the ISO to 800, as the D800 gets noisy over 800, still great but it will lose detail on the low contrast moon once the noise is processed out.
Focused on magnified live view, kept refocusing for each couple of shots, as most would be ever so slightly out of focus, shot by pressing the cable release twice, once to lift the mirror, then again a few seconds later to take the shot, with an additional delay of three seconds set in the menu.
Took about 40 shots and only two made the grade. If you use the TC301 and the 500, with no more converters. you will get a much higher keeper rate and the cropped moon may be better than my full frame with all the glass piled on. Try lower iso as well, the crop will be even better.
PS, on my 400mm I would stay away from the TC16a, AF does not help here, and the TC 301 is better.
Sorry about the wordy description, looking forward to your lunar shoot!
