ELI5: How are there telescopes that are powerful enough to see distant galaxies but aren't strong enough to take a picture of the flag Neil Armstrong placed on the moon?

Galaxies may be far away, but they are fucking massive, fucking bright, and not fucking moving. (At least not moving very much from our perspective)

The flag on the moon is none of those things. Sure it's close, but it's tiny, dark, and whizzing around damn fast.

Also, telescope time is valuable. Most large telescopes are booked every possible minute they can be operating years in advance. Nobody is willing to waste time trying to spot a flag that we already have great close-up pictures of when they could be doing science.
