Well, first of all, you don't have very many pixels on your subject; that's not a good start.

Use a tripod, and either electronic first curtain (EFCS) or full electronic shutter to minimize camera shake. It is best to use a timer, or a remote release.

Electronic shutter on the R5 is not the best idea for any kind of landscape or astro photography due to its reduced 12-bit raw files. EFCS is the way to go.

It makes no significant difference at ISO 12800, or indeed anything beyond ISO 800. Nothing like the four stops extra dynamic range you get by using ISO 800 rather than ISO 12800. They're isn't that much of a contrast range on the daylight side of the moon, but I don't think any sensor you can buy will show more than a couple of stars when the exposure is right for the moon. Planets at a push, but not stars.
