And remember, there are 2 types of night shooting. There are cityscapes and the like, such as these, where you want to put things on a tripod, drop your ISO down, and just capture the image in all its clarity. Unless a lot of movement is visible (planes, trains and automobiles) then slow shutter speeds are your friend - and even when movement is visible, it can be used to your advantage if you use really slow speeds. Then there are star and night sky shots. Here, you want to use higher ISO to allow for more light to get it, but not so much ISO that you introduce noise. Don't confuse the two.
In both types, use a tripod, turn off your VR, use a remote (2 stage, mirror up + shutter activation with a wait in between) or the self timer (5 second delay to allow for the camera to still before the shutter activates).
That's exactly what I did... We were talking about stars and eventually city lights, and I definitely mixed them up... I also did not raise the mirror nor did I use self-timer... will add that to my notes as well!
