Can a big dob (16" F4.5 or so) be easily moved in one piece? I'm thinking about storing one in my garage and wheeling it out, in one piece, onto an asphalt driveway. Also, I'd get a scope with a detachable mirror cell so the mirror is not subject to car exhaust. Do any of you store your scope with mirror in the garage? If so, have you noticed any degradation due to the exhaust?
