What's the tolerance of mounts, and other gear to cold temperatures? We have had lows in the single digits and below zero (F) here in Indiana, as elsewhere, lately. I'd love to take advantage of the first clear night here in weeks but?temps are expected below 10F and I don't want to risk damaging anything (besides the danger of frostbite). I recall reading some discussion of lubricants, but not sure of what else might be an issue.
