I’ve been trying this for some time now, although it’s pretty tough to not have a lot of noise and cheating the shot, considering I live in Los Angeles.

This is a great article with lots of great information. One thing however, if you have noise reduction turned on it could leave gaps in the final image With noise reduction on in, for example, a 60 second exposure your camera will need to wait another 60 seconds or so between exposures while the noise reduction does its work. While noise reduction is operating on almost all cameras you cannot open the shutter to take another exposure. This is because the way noise reduction works, is after your exposure the camers takes another “exposure” with the shutter closed so the hot pixels build up on the sensor. It then looks at the noise that builds up on the black exposure and removes that noise from your original capture During the 60 seconds you will not be able to take another picture, unfortunately the stars will move enough in 60 seconds and there will be gaps in your final layered image. I would suggest turning noise reduction off to limit the amount of time between the exposures.

I know that noise is an issue with long exposures and digital sensors, however, even with the older sensors from four or five years ago on a 30 or 45 second exposure at low ISO noise shouldn’t be that big of an issue.
