Hi dave, nice photos. I'm curious about the peltiers. my dob has a very small fan on it (standard bintel issue) & I'm thinking of putting a bigger one on it. While I'm at it I'm thinking of changing to a peltier instead, Is it a simple case of mounting the peltier where the old fan was or do you need to do what you've done to insulate the whole thing? I'll only be doing visual observing so i guess mirror temps are'nt as critical as when you do your imaging but I'm really getting into planetary viewing & would love to get more detail out of Jupiter & the like.
Ps really good presentation at the Planetarium the other nite
