Long Exposures

[Flies & Photos]

I have a new D100 and I'm looking for advice on taking long exposures with a digital camera. Any advice? I know to use noise reduction, a cable release, and mirror lock-up. When I did this the last time, my image turned out full of noise and was basically indistinguishable. Please help!
