LOw ISO (100 or 200)

f4-f5.6 - depends on the ambient light where you are.

Manually focus the lens at the wide focal length end.

Bulb mode with a remote release.

That's if you want to do one single long exposure. The better way is to do many 30sec - 1min exposures and 'stack them';

This will minimise long exposure noise and also saves you something if it goes pants & the camera fails.

First, you'll definitely need a tripod and a locking remote release. You'll also need your camera to be in Manual Mode and with auto focus and VR turned OFF on your lens. This site will help you:
