Captured May 18th 2021 around 21:50 - 22:00. At the time, the North was still light (53°N). A combination of Red and UV/IR-Cut/L filters were used to mitigate for the sky brightness.
Equipment: Celestron C8 SCT, 2 filters, Skyris 618m CCD camera.
Process: Autostakkert!3 (stack best 20% of 7200 frames), Registax6, GIMP
On the lower left are the craters Aristoteles & Eudoxus, on the right Endymion, Hercules & Atlas ( from Virtual Moon Atlas). The smallest cater I can identify is ~3 miles across.
Next, a 2x Barlow lens was used to drill down on the two crater groups. The 2 filters were retained. Gain and exposure were increased. Best 10% of 2100 frames were stacked.

Nice, Dave!
With your image of Aristoteles and Eudoxus, I took a double-take. There is a flare of light at the surface. I checked it out at Virtual Moon Atlas. It's not obvious, but there is a wrinkle in the Moon's surface near Eudoxus that caught the sunlight. You caught it just right.

That was pure luck - 1 minute either way and the illumination would be different.
