Just as a by the way... I noticed mine were far from sharp this morning, even with it being much better (sharper) earlier.. the lower on the horizon, the more clouds/haze/heat warp/ etc also come into play.. Try shooting the moon on a clear night with it high in the sky and compare to this mornings run... I saw a significant loss in sharpness just from those factors, among other things, but at least I can be one of the thousands (hundred thousands? Millions?) that captured the event.

It took a few tries to get it. Just to add I never had decent success using AF.

Let this be a lesson. If you want a photo of the moon, spend another $2,500 for the newer versions of both products. ;-)a

I totally agree with this. As I was shooting it, I kept thinking to myself how low on the horizon it was so low that I was actually shooting it between two houses. So I do agree this makes a huge difference.

There were some posts about atmospheric distortion in the 100-400 II review thread. The horizon is bad for that but so is distance, especially near the ground.

Since the discussion point is involving lunar photography, here is a shot from the 2010 lunar eclipse, which was the first total lunar eclipse to occur on the day of the Northern Winter Solstice since 1638,
