The moon's a balloon

I thought as it was such a clear night I would take a picture of the moon, it's not as easy as it looks. I have been reading a bit about it on the web and it seems that the moon is actually a sunny surface, so you don't need night settings. I tried one setting .. shutter speed 100 (I think that might mean 1/100 and aperture F16. The results are cropped obviously and not great... but OK enough for me to want to try again when we are nearer fuller moon! The first shot is exactly as taken apart from the cropping, the second has been enhanced.. how did you guess!??
