Another Star-Trail

Taken last night, this is the same tree as my recent post, but with the camera pointing in a different direction:


It's a combination of three ten-minute exposures. I bought an intervalometer, and I had set it to take 18 ten-minute exposures, but all but the first three were ruined by condensation forming on the front of the lens, despite me trying a chemical hand-warmer wrapped around the lens to try to keep it warm, as was recommended to me.
Anyone know a foolproof way to keep the lens condensation-free when doing long exposures on a cold night?
