Canon 600D peltier cooling modification

Finally built a peltier cooler for the canon 600D. Credit goes to Martin Pyott for the originl design:

I had to modify the design slightly due to the aluminium plate snapping and a comedy of errors on my part, such as not being patient enough in drilling the copper plate and snapping a drill bit in the hole.... all learning experiences.

I was going to invest in a dedicated OSC astro camera but this will allow me to get a bit more milage out the old faithful DSLR. I have attached photos of the finished project and Darks (10 min at ISO 1600) and was impressed and surprised at the difference this mod made in noise levels. The cooler managed to drop 7 degC on ambient after running for about 15 min or so. I don't know how cold it will get when running for longer, and know it wont be able to compete with a dedicated astrocam, but any cooling is a bonus, right? At about £35 for the parts this saved me a fortune which will go into the dedicated TEC cooled mono camera fund.

Next on the DIY list are a power box (with power for the mount, camera, dew heaters and RPi: I have already made my own 12v power distribution box which sits on my EXOS2 "portable" mount) and a couple of auto focusers using the MyfocuserPro2 project on sourceforge (the parts are winging their way to me as I sit here). The savings bring that dedicated mono camera all the closer 😀.

Any advice from anyone who has made these projects very welcome (maybe it will help me avoid more silly errors) or ideas for other projects too.

Clear skies 💫

I did one of these a few years ago now - worked fine.

outdoors, it indicated -20C, with ambient temp of -8C

side note I was using Backyard EOS at the time, and I seem to remember it can show sensor temperature.. worth taking a look at the trial version.

Cheers for this.. I will take 12 degrees of cooling.

I have been using APT (thats where I got those darks) and it also reports the sensor temp. I am currently running KStars/EKOS on a dedicated RPi which means that I have everything remote without the need to hook a laptop up. I will likely just run it on max and take whatever cooling I get from it, especially with summer on the way.
