Brian and Joseph, this was shot with a tripod. I use a tripod 90% of the time when shooting landscapes, even when the light is much brighter. So that's not the problem. It is probably not the best image to demonstrate the noise deficiency. This one probably has more of a dynamic range problem. It was late when I posted so I went the easy route and picked a recent shot. I'll have to look again and find one that I know for sure exhibits the noise issue. Thanks for the replies.
