Why not just use the built in noise reduction function that most digital cameras have as an option to turn on or off. The noise reduction function is basically a dark frame applied automatically to each frame, you just have to make sure your interval time allows the camera to process the dark frame which is essentially your frame exposure time. So if your frame exposure is 20 seconds, then your interval time with noise reduction on will have to be at least 40 seconds.
