  1. Canon 1100D Cold Finger Peltier Cooling - WIP

    Hi there, sorry to "hijack" this thread but I'm desperately looking for help :/ I also know that that this post is a bit old, but I'll try anyway ... I have followed all the steps of this tutorial to the letter http://astrophoto-chris.blogspot.fr/p/hypermod-toute-les-infos.html (except insulation around the cold finger for now and I have two power supplies, one for the camera and another one for the regulator/ fans / peltier) but big problem: everything works until the I power cooling: LOTS of lines / interference in live view, and of course on pictures. Completely unusable. I tried everything, changed the cables, connections, and by process of elimination, identified the culprit: it is the peltier module. When I unsolder its wires, the problem disappears. I don't get it, I've been looking all around the internet and couldn't find a similar case. I have spent dozens of hours on it, it drives me crazy ... Please help !!!!
