I was just out in Horsefly the other day, near Williams Lake, in BC, and i know what your talking about, it was about -32 when I was out the other night. I just wear wool socks, Jeans, PROPER wool under-wear(not "panties" underwear). A proper wool under-shirt, a cotton hoodie, a windbreaker jacket, a ski-mask. and gloves which allow the little end cover flip off to reveal my fingers for delicate work. I'll over heat if it's only 25 below, and keep a comfy warm at 30 below. A trick with the hand controller is to stick it down the front of your jacket or shirt, so it keeps warm off your body heat. It will work fine that way.Another thing to do is build a half observatory( a little snow fort =D) and put a little heater in it. Just put a decent sized wall of snow between you and the scope and all should be fine. But you wont be able to turn the scope around, so its really only usefull if you know where you will be observing all night.

All the stuff i listed can be bought at Mark's Work Warehouse. And if the wool under-shirt costs you less than $50, your buying the wrong one.

About the scope freezing up, one thing that you can do is either yourself, or take it in to your scope dealer to have it taken apart, cleaned, and put in a lower freezing point lube.
