As far as autowhite balance goes I am not so sure. I find 4200K on the D800 works. Perhaps it changes slightly with different types of night shots.
These next gen cameras see in the dark so bright images quickly are more than likely possible.
Your tethered arrangement sounds good. Lightroom 4.2 allows this as well.

I will play around with the white balance and see what happens.
I found last night with the bright moon that a faster Iso and shorter exposure gave less detail than a lower ISO and longer exposure. I think it is a matter of experimentation. Personally I would shoot with the lowest ISO I can get away with. Shorter exposure high ISO = more noise and more subs to over come the noise.
You are right these new cameras can see in the dark. I did a 30 sec exposures under my house at night @ 25600 ISO I was amazed at the result, and how much light a little LED can give off. I have attached this to the bottom. To my eyes it was pitch black, the photo has had no processing at all.

Good not to waste the time around the full moon, shows everyone what you can do under these conditions.
Nice one!

Thanks Paul, I am just getting started with this camera. I have a lot of experimenting to do.

Good to see a Mark III image.
And, yes, EOS Utility + Remote/LiveView Shooting is indispensible.

The EOS utility is great, It makes life very easy.
