Bobby1970 Posted March 14, 2021 Share Posted March 14, 2021 I started this ages ago and soon found out that temp control is a must. I was getting good cooling, but the camera was fogging up. Anyway I bought a cheap temp control module from Amazon, made a better neoprene jacket for the camera. Tested it today in the garage. Seems to cool down to 3-4 degrees with no fogging. The three minute dark frame I captured seemed a lot less noisy, still the old amp glow in the corner, but it can be removed using darks, which will be a lot cleaner hopefully, as will light frames. 3 Quote Link to comment Share on other sites More sharing options...
GazAstro Posted March 14, 2021 Share Posted March 14, 2021 Nice job, did the same myself a while back on a ZWO 183. With a bigger fan you might help take the heat away from the TEC quicker and manage another few degrees. But then you'd probably run into frost on the sensor.

I think going sub zero could cause other issues as you say. All I need is a quieter fan as the existing one is a bit noisy. 1 Quote Link to comment Share on other sites More sharing options...
