Thanks Brent. I've temporarily fitted a large 120mm fan next to the secondary. I have it running fairly slow, but due to its size it pushes quite a large volume of air over the secondary. Judging from 1 nights use it does seem to eliminate dew forming on the secondary, but I need some more clear nights for testing beforee I decide to mount it permanently. It's mounted with rubber bands at the moment to eliminate vibrations, and when viewing the Moon though a 5x Powermate I couldn't see any induced vibration at all so it's very promising.
