Would humidity affect moon pictures very much because it has been close to 100% humidity lately and I just thought about that. I just can not seem to get a really clear shot.
Absolutely. Cold, clear, dry nights are best for attempting moon shots.
Here’s one I took last year with my Sony a200 DLSR. The moon was so bright it hurt to look at. ISO was set at 200 and the shutter speed was 1/500th. I used the 75mm-300mm lens.
I hit the picture with a little sharpening and contrast enhancement, but not much.

I do prefer to shoot pics of the moon when it is not full. You can capture more of the surface texture rather than just a flat looking disk. This one is from back in July of last year.
