Thanks for the info.
Lets do some calculations:
ZHR says 20 meteors/hour.
My StarTracker will track for 3/4 of an hour before I have to reset it. This gives a potential 3/4 * 20 = 15 meteors/hour.
With my camera on wide angle (~ 35mm) I will only be aiming at a small section of the full 360 deg. arc around the radiant point. Lets say 60 deg. for arguments sake.
Therefore the number of meteors available to me is 15 * 60/360 = ~2 meteors/hour.
My camera has a max. exposure time of 64 secs. It then spends another 64 secs. processing the image before it is ready to take another shot. This gives me a 50% duty cycle. Hence my 2 available meteors/hr becomes 1 meteor/hour.
I can live with those odds. I'll have a crack.
