D200 first Night Shots

I tried it out at some different ISO's. Here's one at 160:
These at 200:
This one is really smooth at 100. I missed the focus though so it's blurry:
Critique and comments welcome. I think there are some artefacts introduced with Flickr's resizing. SOrry about that. They're all different times, most between 4 and 13 minutes.
I think that the D70 actually beats the D200 at ISO 200, but of course the D200 at ISO 100 is much smoother. I'll have to try a comparison at ISO 200 and take a closer look, but iso 200 here looks considerably more noisy than I'm use to on the D70. This is going to be a challenge as the pictures are going to be 2x longer, and battery power is significantly shorter on the D200. I do love the bigger viewfinder, much easier to compose these low light shots. One nice thing is that amp glow was fairly minimal (the iso 100 shot was over 1100 seconds, and the ampglow was easily cloned out). so I might just turn off Long exposure NR.
