I just found this link but I do not think it involves a Peltier cooler:

As I mentioned, my concern (while wanting my own cooled camera) is what I have seen with other efforts, I received the Meade camera, fan, cooler and electronics from a member some time ago and as I mentioned he was using a cold finger, the Meade had a heat sink back on the camera body (one piece alloy seriously hacked with a Dremel) and had me questioning what it must have been like having the $1,000 initial camera purchase price to throw away and play. I tend to work with old junk. I did get the sensor producing a signal and did cut a decent piece of alloy to fit in the hacked out heatsink region but signal and no picture so I put it away and was lucky to get an affordable Player One in new condition with the 178 colour sensor. The later model Neptune has larger pixel size which are more suited to my longer focal length old telescopes but on a pension it's what I can do, when I can do it.
One day I'm going to have an amazing astronomy camera if the lotto Gods ever permit such an event, lol.
