@drsridhar First, clear sky, no moon and very little light pollution (which is hard to find). Tripod. Camera set to manual, ISO 1600-3200 and f5.6 or 8, you have to experiment to find what works for you. Focus at infinity, again on manual. I have failed to get the focus correct many times and have wasted many hours because of it. I also take the photos in jpeg mode. That way I don't have to convert the image more than necessary. I found that setting the white balance on the camera to "incandescent" removes the blue from the image, giving a darker background.
I have a NEEWER Digital Timer Shutter Release Trigger Remote EZa-N3, set at 30 sec exposure, 5 sec in-between as seen by the gaps in the straight lines in the photo above. Max number of images that the shutter release will allow in 399, which is roughly 4 hours.

all the images are stacked using StarTrails, found at http://www.startrails.de/html/software.html. Not only can you do star trails with the program, you can do sunrise/sunset photos http://365project.org/byrdlip/365/2014-02-19
