shutter speed slower than 30 sec.
 
I have seen some great photos of stars and the shutter speed is often 2-4 hours. But seeing what cameras they are using, the minimum shutter speed is listed as 30sec. How can you keep the shutter open for so long?

You need to use what normally called the "bulb mode" which you need to pressed once for the shutter to open and a second time to close.
