This often includes, but is not limited to, "Noct" lenses. Apparently the trick is low coma and flare/reflections.
Also, many non-Noct lenses which do well are not made by Nikon. As it's a relatively small group of lenses, maybe you should do some more investigating, there are some astrophography sites, or repharse your original question.

Have fun!
Standard 50mm F1.8 Nikkor is your best bet. Use a piece of tape to lock the lens at infinity. A heavy duty tripod with a good lockable head and maybe some sand bags. If you use a nice quality locking cable release and a piece of card in front of the lens you don't need mirror lock:just set the speed to B with the card over the lens, lock the shutter open and then remove the card. Try 75 minutes at f 5.6 for a clear sky beginning 2 hours after sundown facing North using 400Asa film . If you are shooting during a full moon you may pick up lunar illumination. Aircraft will also leave trails.
