White balance zoom setting, or the focus setting has been changed, then you’ll need to focus your lens on the far distance. Try turning on Live View, and find the brightest object in the sky that you can see. You can then zoom in on the Live View image using the magnify button on the back of the camera (not the zoom on the lens), and adjust the focus manually.
Even when using this method it can take time and patience to focus accurately, though, and you’ll find the whole process rather easier if you give your eyes plenty of time to become accustomed to the darkness. To do this you’ll need at least 10 to 20 minutes on location without looking at any bright lights, using a flashlight or even activating the rear screen on your SLR.
Once you’ve focused, you will need to take a test shot using the settings that you have pre-set, and then check the exposure. The results should appear quite dark, with little detail in the foreground, but make sure that the stars are clearly visible. If your test shot is too bright you can use a shorter shutter speed, such as 2 secs. If it’s too dark you’ll need to adjust the ISO to a higher value rather than using a longer shutter speed, to avoid recording the movement of the stars.
