It worked well at the SVAA camp last weekend - 3C at 4am.

At Alistair's suggestion, a dewpoint calculation in the code switches heating near dewpoint to maximum. The rest of the time heating is scheduled in response to humidity as a convenient reference. The lens suffers from moisture ingress and condensation on an internal element - running heating all the time seems to help keep it dry.
