Some people use water chillers. I know Fred simply put chunks of ice in a bucket of water.

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. |
