I'm going to spend 3 weeks in a Bortle 4 area with nights going down to -10 Celsius (14 Farenheit).
I removed batteries from my setup and I'm using only cables (USB, Dummy Battery, etc).
I also have 1 dew heater that in the summer I strapped in front of the lens.
What other things do I need for my gear to survive/work in cold conditions?
Is the LCD on my camera going to freeze? Do I need more dew heaters like for the other elements in my lens?
