Hey Webster,
I have used my camera here at pole even when it was -100f. I have froze it a few times, but just bringing it back into the staion and letting it sit, then it works fine. Just keep it warm in between pictures. And bring extra batteries, the cold sucks the life out of them, actually bring rechargable, and a charger, since you will have a plug in where ever you stay.
As for the laptop, mine is fine after about 6 or 7 trips outside from the plane to the station to my berthing. Just remember to let it warm up before using it, and don’t let it sit out, but I shouldn’t have to tell you that.
