I would like to know how much these images overlap or at least see a few of the single shots. I’m curious what the inputs look like.

I found this article[0] that shows the gear he used for the images discussed within, but that was from 2022. He used a Celestron NexStar 8SE with a Canon EOS 1200D. If you really want to know, you can look up the magnification of that particular scope with the sensor size of that camera, and you can see how much of the moon would be imaged in a single snap. That would at least get you a closer guess. However, how much he overlaps is still a question. For this particular final image, it sounds like he's completely overlapped each image multiple times since there's 81,000 images used.

  You would be doing "lucky imaging" to get around atmospheric disturbances. Basically, you take 100 images with <100msec exposure times. You check which ones were good, and discard 95 of them. Then you overlay the good ones. That would explain the high number of images taken.

    Yes, except those numbers will be a lot higher.

      81,000, so 810x higher which definitely qualifies as a lot in my book

    There's informed ways to increase your luck like choosing a location at the highest altitude you can, pick a night with cool crisp air vs hot summer air, be fortunate to have a storm system roll through and clear our just before you shoot to clear out the air. TFA says he is Kurdish which would suggest to me that finding a spot in the mountains with some altitude was probably not out of the realm of possibilities.
