Well I have gone ahead and ordered some bits for this project. I went with one from PCcasegear, the GPU one mentioned below. I found a spec sheet for it and the base is 50x50 so that is fine for the TEC, a little big but not an issue. I will need to make a small carbon fibre bracket to hold it fast to the cold finger, sandwiching the TEC. It has the tube barbs on the end so that is good. I ordered some flexible tubing. Still looking at pump and reseviour options, the pump will need adequate lift pressure to get to the camera. I also need to work out how I will mount the pump and the radiator in the observatory. Of course it's going to be hard to move the camera into the house now as it will be tethered to the pump etc. by the tubes.
