you will find that it still takes a long time to cool the mirror to the ambient temperature exactly, but and a big but is that installed with minimal vibration, then the movement of air up the tube stops the eddys and the seeing improves. hence leave it on!!
I believe starkler has this happen to him. I also have noticed it. Mind you, the bottom is sealed, so the air must move up the tube, not bounce of it and back towards the ground.
