Just got my Optishot and I'm working on a garage based setup for the winter.

Can anyone tell me if I should be concerned with operating a projector in an unheated garage during the winter in temperatatures at or below freezing?

I'm trying to decide whether to get a short thow projector installed on the garage ceiling; or a regular throw projector, live with some shadow and bring the projector in and out each time I use the Optishot.

Thanks for any advice.
