I would not switch it off, can you got to say 1 sec instead off 30 sec? Then you will 
have less interruption of the trails. So instead of 13 times 30 sec, you take 390 
times 1 sec.
Well, actually, as you take a lot of pictures, changes are that random noise of one 
picture is canceling out the noise of another. That doesn't work well with just two 
pictures, but with a lot it might work very well.
Just some ideas, trial and error makes the master.
