After about 30min in -10C to -20C temps the focuser stiffens up considerably. BUT because focus is so fast it is really not really a problem since only a slight rocking of the knob is needed to cover most usuable distances. Never stayed out more than 1 hour at time in those temps before hopping back into the car to head to a new spot though. Perhaps it eventually would freeze solid! Despite the bright sun reflecting off the snow and frozen lakes there seem to be no isssues with glare or stray light either. Also got to do some star gazing and confirmed mild field curvature is the predominant aberration in the outer field. Otherwise, stars focused to tight pinpoints with brilliant color. These are VERY NICE optics! Finally, some folks on CN bino forum are having issues with the eyecups not extending far enough for the 17mm of eyerelief. I think this is a blessing since it allows air to circulate and keep the oculars from fogging and still allow the full FoV to be seen.  cheers,Rick</blockquote>
