Also - gather there is no need to peltier cool a mirror like this and fan cooling is more than sufficient?

Hi John,
I'll use 2 flexible steel wires which will be supported by old antenna parts as in this image, they are sikaflex'd to the bottom only.
Yes no need of a Peltier as the Observatory is air conditioned and the top cover fitted extractor fan will be run prior to the roof opening and natural convection through the mirror central hole will work continually during use.
Cheers, Phil
