Peltier cooling for Newts update

Finally have found some time to make a start on this project.............so, went to dick smith, the 12volt fridges were $19.95, so 5 of them, 3 x 10amp switches with red l.e.d, some cable connectors to try and clean things up a bit (sorry asimov, but John K and Mike are neat people) and a $49.94 jump starter to power things.

Over on SCP we decided saturday night / sunday morning, we were imaging saturn no matter what the weather was like.........so i left my scope out in the pouring rain and shorted the battery charger..........soooo, $49.95 for a jump starter just like Mike's was the way to go.

John K's will be the lid design ie cooling the mirror from above and needing 3 peltiers. Mike's will be like mine and cooling from below.

Paul Haese is also making one with 5 peltiers for his 18" SDM and will be a lid type.

Here a few piccies, more over the next couple of days
