Peltier Cooler / Heater

The condensation on the primary has been given me the "you know whats" lately.
So with the primary mirror actually going under the ambient by as much as 1.5 degrees, I thought I may as well use the little voltage switcher that came with the Dick Smith Fridge.
So, now my cold plate can become a warm plate to help bring the temp back up and or remove condensation.....
Now for the clouds to go away!

Thats really being very creative. I hate dew and simply give up when its about. There is nothing more frustrating on a long exposure to realise it has landed.. at first you think mmm nice shot what a lot of nebulosity and you blow the image up and its useless.
