Just gotta love trying to think outside that square....very interesting discussion.
Dave your idea is so interesting. At one point I was actually thinking of simply taking the whole mirror assembly out of my scope (only 3 large bolts) and just sticking it in the fridge until the mirror was "chilled" to the right temperature. Problem: A bit of mucking about in doing this.
The "sealing" idea could be a great option for my scope as already the steel dust cover does exactly that over the tub, it's basically air tight sealed.
I am going to buy some ice packs in the next few days and try that option first, do some temperature and dew monitoring together with sealing the mirror in it's tub with the ice packs as well to create some uniformity in cooling it like inside a cooler box (I take on board the dewing issue) and I will report back.
Anthony with regard to the potential dripping of dew issue with Peltiers on top, perhaps turning the scope at 90 degrees would overcome this?
Lastly, silly question, but are peltiers a heat pump? and if simply cold air is required does a small heat pump as used in small domestic air conditioners achieve the same thing?
