I will not describe in words what I’ve done with the Canon EOS 700D, i’ll just describe the peltier cooled part in pictures.
I bought this Camera for 165 Euros used on ebay-kleinanzeigen and astromodified it myself using this tutorial.
I deviated from the tutorial by getting out all filters and not replacing them with anything at all.
After that I cut a whole into the back of the Canon EOS 700D, big enough to fit cooling fins onto the back of the sensor array. I glued it on with warm (not hot!) hot glue. The rest is in the pictures… enjoy!
