astrosathya Posted January 17, 2020 Share Posted January 17, 2020 Just thought i'll bring this up as a point of discussion. Today, cooled CMOS Astro Cameras are available in plenty. QHY, ZWO and other variants of the same camera are selling for very reasonable prices. However, there was a point of time when astrophotographers used to cool down their DSLR's as a cheap OSC alternative to CCD cameras. Give a choice, I would've purchased a dedicated CMOS OSC which can cool to 40 C below ambient, but since I had a Canon 500D which I had self modded, I requested a friend Kaustav Chatterjee (an avid model railroader) to cold mod my 500D (he had cold modded his 1000D long back). This newly modded camera has a TEC12703 single peltier and cools to approximately 20 below ambient.What do you guys think? 1 Link to comment Share on other sites More sharing options...
kirkster501 Posted January 20, 2020 Share Posted January 20, 2020 Good work! DIY is mandatory in amateur astronomy 😀 does it work well? Link to comment Share on other sites More sharing options...
Phil Posted January 21, 2020 Share Posted January 21, 2020 (edited) I have just completed a similar project. Mine seems to cool the sensor down to 15 or so below ambient as reported by the Exif temp. Created for my EOS 600D. It will keep a steady Exif temp of 5 deg C on 300s subs if I put a 15s pause between exposures. Could possibly go colder when the ambient temp is sub zero but it's a balance between cooling a power consumption. It is using a 5 amp TEC.

alessandro83 Posted October 25, 2021 Share Posted October 25, 2021 Guys i have an EOS 2000d reflex, i would like to create a cooling system but i don't know where to start. I would like if possible to apply the peltier instead of the display, could you help me? And if someone has a functioning cooling system that they don't use anymore, I'll gladly take it 😅. I do not expect 50 degrees lower than the ambient temperature, but at least reduce 10/15 degrees in the summer. Thanks for all the useful tips. I know there are dedicated astro cameras but currently the pockets are a bit empty Link to comment Share on other sites More sharing options...
