In the posts for Dew control it has been recommended to run the mirror cooling fan to prevent dew build-up on the secondary mirror.
There are Fan Speed controllers for computer fans that could be adapted for scope use, some controlling up to 4 individual fans and some with remote control. The following link shows some of the devices available and coupled with a bit of Astronomers ingenuity might be a useful device.

If anyone has had any experiece with similar devices maybe they could let us know?
