Acclimatise your Telescope - A&NTV Shorts

If you want to see fine detail with your telescope, give it time to adjust to the outdoor temperature. So put it outside even before you get your hat, gloves and other observing gear.

A group of us went out on a beautiful, very cold, dry winter night. We let the scope cool down for about an hour. The different materials cooled and shrunk at different rates - even the main lens cap fell off on it's own because it's material shrunk differently than the tube. The new guy got excited and jumped out of the warm truck to check the scope. He stuck his eye up to the eyepiece and instantly flash froze his lower eyelid to the eyepiece. We took the eye with the attached eyepiece back to the truck to thaw and detach from each other. After about an hour of hysterical laughter, we explained to him how he needed to keep his glasses on in freezing temperatures, Good thing he didn't stick his tongue to a light pole or something...
