P= IxV - so you've got 18 x 12 = 216watts for an hour, or 113 watts for two hours or 56 watts for four hours

Thanks. Not sure about the dew heater yet. I want to get the scope and see how much dew there is around here before seeing if a heater is needed or not. I was just trying to get a feel if an 18h was ok, or if I am dreaming. Comes from a dob background, I haven't had dew problems in the past (nor the need to power mounts or cameras!).
