FWIW, here's my eclipse shot showing some stars around the moon:

Here's a pair of mine (reduced for flickr) that show some
stars/planets around the moon.

What's amazing to me is, when you look at the full size images, how
much motion blur is visible even at a 2 second exposure.
The one I linked above is also 2 seconds and ISO 100, and streaked. That's too long, the ISO should be turned up (& aperture opened?). Another route is to align & stack several short consecutive photos, the rotation of the moon will blur at some point too.

The rotation of the moon will not cause blur because it rotates at the
same rate as it orbits. That's why there's always the same dark side
of the moon, and light side.

The moon rotates in the sky with the rotation of the earth.
From our point of view on the earth, the moon rotates as it moves
across the sky with respect to our local horizon.
For example, when the moon is rising, the north
pole of the moon would point approximately to the left
in an image, but would point to the right when it is setting
(from the northern hemisphere).
