Laptop exhaust affects imaging?

[Cosmic Geoff]

After a number of poor results with planetary imaging, I am starting to wonder if the apparent poor seeing is caused by the warm air exhaust blowing out of the laptop.  I have had the laptop positioned a few feet away from the telescope dewshield and blowing air in that direction.  Aiming at Jupiter the dewshield etc is just a couple of feet higher than the laptop. 

Next time I'll try to remember to put it on the other side of the telescope so it blows air away from it.  But there are plenty of other things to think about while I am out there.
