Regulated peltier cooling mod for Canon DSLR
Earlier this year I set about to install a regulated cooling mod for each of my two astro imaging camera: a Canon 1000D and a Canon 450D.
I decided to go with a cold finger rather than a cold box as I was intenting to use an OAG, which due to the clearances required would have been incompatible with the cold box designs I had seen. The cold finger was made out of 1mm thick copper sheet, which was cut to size with a hacksaw. The cold finger is inserted into the gap behind the CMOS sensor, as shown.
