I’m going to fit Peltier to my DSI Pro also. I tried the camera last night and find out that on coolish night it got a lot of hot pixels. That means that it will get much worse in the summer. But I’m waiting for K140B - NEW TEMPERATURE CONTROLLER KIT from Oatley Electronics. With temperature controller the CCD chip should be kept at reasonably constant temperature therefore reducing number of hot pixels and number of dark frames required. It should also reduce power consumption somehow ( if not set for maximum cooling). I will also make little box from polystyrene to fit over camera heatsink with square hole in the middle for hot heatsink and fan. Heatsink on the camera has been designed to radiate heat away and it is inefficient to cool such a large piece of aluminium that is exposed to ambient temperature
