At first it may seem that the relative distance of objects is a factor with respect to seeing conditions. Reality is it makes no difference at all. Doesn't matter if it's the Moon or the furthest quasar, focus wise they are all at infinity. And they are affected by seeing conditions in the same way.
The main difference is only the relative size in the eyepiece of each that things MAY appear different. But if you look at a crater that's the same angular size as say Jupiter, the details of each will be affect n exactly the same way and amount. Contrast is another way things may appear as a reason for differences, with the Moon a stark black and white and surface features of the planets much less stark, but seeing affects everything the same way.
