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.

But there's no need to shoot the moon at ISO higher than 100. And EFCS produces no shutter shock.

High speed continuous shooting and silent shooting are probably the only cases where ES is justified.

Also ES limits the exposure time to 0.5 seconds. Basically it's totally useless for landscape/astro.
