Looks pretty good, It is definitely harder than most people think, I know.

I think Troll offered some good advice, and I agree I would try shooting without the CP, that alone may alone you to quicken your shutter speeds and therefor avoid the slightly out of focus appearance.

Other than that just watch your WB (not to say its off in your pic). I know the moon can have a yellowish tint to it some nights like it does in the OP, but that does seem to be fairly off white, so I would just be adjusting it before almost every shot.

ibepressin: that is a very nice example!
