Thanks Storm. I tried to keep the ISO low (800 or 400) and shot with 3 seconds at around f7.1. I noticed that things were looking out of focus but soon realized that 3 seconds is too long and creates blur from the moons movement. It has the appearance of making it look out of focus when in reality it is movement blur.
So I changed to a 1.5 second exposure and upped the ISO to 1600. I think these were shot at f7.1 using my Sigma 70-300mm zoom. I was fully zoomed into at 300mm. The shorter shutter speed turned out to be the key. The noise wasn't too bad at 1600 and I tweeked it with the Topaz Noize plug in and then sharpened the detail a bit using the Topaz Detail plugin. But out of the camera they were still pretty nice.
lastly I shot in both jpg and raw. The first picture is jpg and the second raw. I didn't see a lot of difference in quality. I'm still undecided on the whole raw vs. jpg and this was just another chance to examine both options.
I would never have guessed that 3 seconds would be long enough to create blur from the movement of the moon.
Other setting that helped me were to set for center spot exposure and place that right in the middle of the moon. I the display to turn off so I could look through the viewfinder without being blinded. I found out that you can still push the play button and the last picture will come up on the display so I could zoom and review the historgram. The zoom is what keyed me into the fact that things were sharper at 1.5 seconds.
Of course I used a tripod. I also set the shutter release for a two second delay to allow the camera to settle from the mirror movement and this also shuts off the image stabilization which isn't needed. Some say the image stabilization on a tripod can create other problems but I don't know one way or the other.
That was pretty much it. Surprising also how dark the moon becomes. I can shoot at around 1/500 for an ordinary full moon.

Jimr, I didn't know that about Uranus. I did a little research and it seems that it is pretty likely Uranus is the "star" at 8 o'clock.
Originally posted by jimr-pdx One of those 'stars' below the moon is supposedly Uranus; it should be greenish-grey which implies the brighter one in both shots.
I have a few shots to look over also.
