Adjust your diopter how you will shoot, glasses on or off.
Look at only the focus screen indicators (grid, AF indicator) against an out of focus white wall. Get the focus screen in best focus for you using the diopter adjustment.

A. no need to use manual focus just because you are in manual mode.
Second. focus, set timer, use mirror lock up, images will be tack sharp ( for the moon shot).
C. Practice dont make perfect, PERFECT practice makes perfect.
Take your time, shoot, look, see what ya got, adjust from there.
Fourth. get "into the moment" Focus on taking the shot, pay deliberate atttention on the mechanics. Dont let the subject blur what the goal is.
Something it took me time to overcome "Gee what a purdy flower" get home and the shot is JUNK cause I failed to concentrate on the details of taking the shot, WB DOF focal point, etc ad nausuem.
Most of all ENJOY, taking the shot should bring equal joy to processing the shot and hanging it.
Just my opinion

I agree with PNagy on this one. Intuitively, I used to think that moon shots would require long exposures. However, on a clear night with a full moon, setting your camera's meter to spot mode shows that the surface gives off quite a bit of light.
This one isn't as sharp as PN's, but it shows the concept. The shot was taklen with a 50D, a 70-300 EF IS USM set at 300mm & f8.0. ISO was probably too high (640) and shutter speed was 1/800" on a QuantaRay tripod. Shopped for levels, contrast & slight color shift to kill the yellow cast (Yeah, I know I went a little overboard).
There's a new moon tomorrow. I'm going to try again with my 5D MK II and a 100-400 EF zoom w/ & w/o 2X teleconverter on a Manfrotto tripod (WAAYY more steady).

others have already mentioned mirror lock-up. i thought i had everything just right, stir blurry. mirror lock-up was the final piece to the puzzle. @600mm, if you breath heavy the shot will be blurry. :)

Just wanted tell everyone who volunteered information a big thanks.
I could not get a great picture tonight due to a very light cloud cover, but I did experiment with a faster shutter speed and that definitely helped the focus clarity.
I really appreciate the technical discussion for solutions, because then I understand the why, not just the what.

Your camera manual will tell you how to adjust the diopter, it depends on your prescription whether your diopter will compensate for your vision, if you have severe astigmatism probably not.. Usually it is easier to remove glasses, you may have to get used to wearing them. Two accessories that may help are a rubber eyecup or a prescription diopter (talk to the optician at your optometrist for this).

I'm going to go out a limb and mention another often-overlooked problem. Once in a while a photographer will set up a shot like yours, set the lens manually to infinity or to the end of the focusing range. Many lenses will, at that point, be focused "beyond infinity" (no jokes about Buzz Lightyear) and the shot may be out of focus. Some say lenses don't do this, but the fact is that the markings on the barrel are not necessarily that accurate.

Quite true. I never set to infinity.

Pigpen, that's good thinking. There is a way though that the original questioner and others can learn to use the focus markings; it's called "modified scale focusing" and is achieved on lenses with DOF scales. Set your infinity mark at or slightly inside the "long" end of your DOF scale. There are a lot of articles on the subject, and I'll bet a lot of people on UHH can explain it better than I can.

Why remember that the earth and moon are moving through space if it it is not apparent here on earth?
Also shouldn't the earth rotation be 24,000 miles per day instead of mph?

The thing is, it IS apparent on earth when you look through a telephoto lens; the greater the focal length, the more apparent the movement.
You're right, Earth's rotation is roughly 1,000 MPH at the equator, so about 24,000 mi/day (http://www.universetoday.com/48322/speed-of-earths-rotation/). However, the moon goes MUCH slower: ~10 MPH (http://www.newton.dep.anl.gov/askasci/ast99/ast99142.htm). When you look through the viewfinder, you actually see the moon moving across it. In some cases, I'll "lead" the moon much like a hunter leading his prey. If I use the self timer while mounted on a tripod, I set the lag time as short as possible in an attempt to center the moon in the frame.
