When I bought my camera (second hand) it has a secondary cooler and water cooler installed. The secondary cooler didn't work so I removed it and purchased a new peltier device to replace it. It needs a 30mm square peltier and the closest I could find is a called a TES1-12703 from
these guys.
I bought 2 for US$19 plus postage. (so now I have a spare).
I run it with 13.8V from a marine battery.
I think it is a bit more hefty than the one that SBIG uses hence the good temp drop.
My water is just a 20L drum that sits in the observatory and is at room temp. I don't change the water much as I'm on tank water. It seems to stay OK.
