Interesting. Radiant sky temperature in La Palma is also about 30C lower than ambient.
I have never seen dew anywhere except inside a SBIG camera after the desiccant needed renewing. That was excusable because it was generally run at -20C.
Perhaps having the scope inside a dome is advantageous from this point of view too.
