Here is my Extreme Close-up photo, Looking inside the Impact Crater Copernicus and it is 12,467 feet deep(3.8km), and approximately 58 miles in diameter (93km).  One of the larger impact craters on the Moon.  It was named for Nicolaus Copernicus, who was a Renaissance-era mathematician, astronomer, and Catholic clergyman who formulated a model of the universe that placed the Sun rather than Earth at the center of the universe.

I captured this with my C-11 SCT Telescope & QHY290M un-cooled Cmos camera, 2x Barlow, 15ms exposure, 765 frames stacked in Registax6.

Seeing wasn’t the best, but I took a shot anyway, and it does show a decent amount of detail,

I captured Copernicus crater from my backyard in Dayton Ohio, 09-10-2020.
