I have found that even a short bag over the dewshield/lens, and another
short bag over the entire focuser (with a DDCAP in it), with 2 rubber
bands
on each end sealing the bag to the scope, works great.

Sure, moisture condenses all over the outside of the tube assembly for
a while, but the bagged ends stay dry.
