Hmm.. I'm sorry but I'm thinking differently. I'm doing exactly what you are KG - on my 12" LS200GPS. I want to heat the air near the corrector plate - but I don't want to heat the plate! You end up with all sorts of optical problems if you heat them directly - you are not looking to heat the scope parts, but to heat the air near the plate by only a couple of degrees to stop it from reaching dewpoint. The only reason that other systems (such as those external strap-on jobs) require good transfer qualities is that they rely on transferring heat THROUGH the OTA walls to get to where it's needed. With what you propose - you're already there. Tell me if I'm wrong, but I don't think that you want your scope to radiate heat.
I'd like to hear what others have to say on the nichrome wire - I've heard that it has disadvantages over resistor arrays but I need clarification.
Cheers
Chris
