HI Shane
Er.....what was it you were trying to see with your 7mm that's 'further away' than the moon?
To my mind, if the moon is sharp, then anything else should also be in focus. Of course, as you pump up the power, you show up any alignment errors with your optics. Perhaps you have collimation issues? Have you collimated and star tested your new 'scope?
Or, maybe the seeing is simply not good enough for the 7mm (although 178x for a 10" newt doesn't sound too much mag to me, even on a poor seeing night).
I'm sure you'll get the advice you need from other, more experienced members of the forum.
Good luck with it!
Dave
