Øivind,
Thank you.
Capture details: D850, AF-S Nikkor 500mm f4.0D IF-ED + TC-14EII, mounted on Sachtler ENG 2 CF HD / Video 18 S1. Nikon lens foot replaced by Wimberly AP-554. Analogous to a suggestion that Birna made years ago I've inserted a piece of thin wall aluminium tubing covered with a wrap of durometer 70 rubber between the foot and the lens barrel. This really does help stability. Release With MC-30A. Deliberately a bit underexposed to preserve some detail in the brightest areas- 1/100, f4, ISO 64.
Processing Details:
Post 918- Developed in Photo Ninja- whatever version was current in March of 2021. Development "as is" except details slider moved to "5" and minimal sharpening at radius of 0.5, sharpening set to "60" - "50" is the default. Exported to Capture One as a .tiff with .xmp.
Post 926- Developed in Capture One. Exposure reduced by 1/6 stop to minimize burnout.
Both Posts- I've reduced contrast to best show detail of both the brightly illuminated and rather dark areas then brought up brightness until just a hint of burnout is present. Then I converted to B&W as follows: blue channel 100, magenta and cyan channels -80, red, yellow and green channels -100. At least when using this lens and converter the image appears cleaner; this despite the long held reputation of the blue channel being the noisiest. I then applied blue and yellow split tones to the image in 926, and a very little blue tone only to 918. I then ran through the normal (for Capture One) juggling of noise reduction and sharpening parameters to achieve the best image I could get from the raw/tiff file and then followed up introducing just a bit of adjustment with the clarity, structure, and dehaze sliders- I can't go far with any of these without degrading the image with artifacts. Sharpening radius set to 0.3 for the image shown in post 918 with no export sharpening applied, Sharpening set to 0.5 for the image in post 926 with export sharpening set to 0.4, 80% for the posted .jpg.
I've not used Topaz Labs products here. To me it seems as if Topaz, in making the Sharpen AI program/plug in easier to use over the past few years, that there is now considerably less control of the artifacts that are generated. When using Sharpen AI 5.6.1 I spend more time cleaning up the artifacts than the result is, to me, worth. I do keep a copy of Sharpen AI 1.4.6 on my system- in that version when the sharpen and remove noise sliders were set to about 1/6 to 1/5 of what the algorithm "recommended" there was an improvement that often did not require extensive retouching. I'll note that sharpening function in version 3.3.2 of DeNoise AI is less apt to produce problematic results. Here, I didn't observe any worthwhile improvement, at some other times with other subjects, I've been quite pleased with the result. For what It's worth I also tried the motion blur function in Focus Magic(a deconvolution type sharpener) version 500b- greatly magnified there was a slight improvement, but given that I processed the image for viewing on the internet I did not save the result.

ColinM,
Thank you. The photos of the moon I've posted were taken at about N34°49' 25", W96°34'26"
At full moon 50% of the moon's surface is visible. Over time the orbit of the moon allows about 59% of the moon's surface may be seen from earth.
A worthwhile discussion about your question about the apparent rotation of the moon is at
