My dew heater failed right as the Orion Nebula came into view

I was out near Sedona last night, had everything set up for a two-hour exposure run on M42, and the temperature dropped fast. The heater strip on my corrector plate just quit, fogging the whole lens in about ten minutes. What's a reliable brand you all use for cold weather imaging?

Honestly, that's the worst kind of gear failure. I've had good luck with the Kendrick ones, but I'm also the guy who forgets to bring spare batteries.

Velcro a spare to the inside of your case.
