Clear But VERY Cold Nights

The Orion Nebula is in the eastern sky at the moment.   Unfortunately, clear skies in winter means nothing holds in the heat (such as it is).  Monday night should be clear so with some advance planning (electric jacket, thermal underwear, snow boots, put telescope outside at Sunset) I should be able to dash outside for a few minutes to verify that M42 and M41 will be good enough through the Televue for an upcoming public school star party.
