Outrageously "cool" idea, so left field, love it, but given astroimaging (if your serious, and youd have to be to set this up) requires say, 10 or more hrs of exposure time per project, wouldnt this require gallons of coolant, applied at very regular intervals?. So then, a (even high power) peltier would be far more cost efficient?.
