Paul,
I found that a small fan in the observatory, blowing air out of the dome shutter, seems to pull air from under the flooring very quickly to equalise any thermal differences before I start doing any observing/photography.
Seems to work for me and the dome really insulates the scope from any wind buffeting that may occur, unlike when I imaged outside previously.
I really am chuffed with the whole setup now and cant wait until my new camera comes and I can start NB imaging.
