I agree with Wayne.
I can't pick a problem with the focus you have achieved in these images. Did you reduce their size to post them? Being a single shot there may be some softness due to seeing which could explain maybe why you aren't satisfied with the results on camera.
The best solution for seeing issues is to take many shots and stack and sharpen them using say Registax, K3CCDTools or AviStack.
Generally focusing on a star is easier than focussing on a planet or the moon, so a Bahtinov mask can come into play there and take the guesswork out of focusing.
