Peltier Cooling ASI Camera
Finally tested a peltier cooler for an ASI Camera. After a few runs I managed to get the temperature down from 30-35 degrees down to 12 degrees with a 100W TEC1 12712
I simplified the construction using a heat sink and fan connected straight to an aluminium disk screwed onto the ASI 120MM. I have not shown the stubby cooler which was my insulation sleeve. Perfect fit for the ASI.
Did not fog up the inside window at this temperature, but the outside when I took off the stubby cooler.
Maybe I will work up to trying on a ASI 1600
Ran the little DiaMec 12v battery down in about 20 minutes though. Perhaps i need to try a lower wattage or find a better power supply..
I took some sample images with the camera covered at 60sec 14 degrees, 30 sec 23 degrees and 30 sec 35 degrees. Not sure how much better this will be in practice.
