Ohh, #Eratosthenes , one of my favorite craters. You've captured it well.
Here's my best attempt with my #ETX90

The region around #MontesApenninus including #Eratosthenes & #Archimedes at 16:59UT 6th Feb '25. Taken from Oxfordshire, UK with a #WilliamOptics 70mm refractor, #Celestron 3x Barlow & #ASI120MC camera. Best 50% of 1,000 frames #LunarPhotography #LunarCraters #LunarMountains

I notice #Eratosthenes Crater in the lower right of your image. A smaller crater than Copernicus, but with an interesting 3 mountain formation at its center.
That's another of my favorites, and I was able to catch it pretty well with my #ETX90 on one occasion.
Flat Earthers are really just irritated that Eratosthenes figured stuff out before calculators, telescopes, and electricity.

"#Eratosthenes’ only tools were sticks, eyes, feet, and brains,
plus a taste for experiment. With them he deduced the circumference of the #Earth with an error of only a few percent, a remarkable achievement for 2,200 years ago."
