Moist on the inside DSLR screen when cooling

[AstroRookie]

Hello,

I recently asto-modded my Canon 500D. Now the next stage is to try to cool it. During my tests, I noticed that moist builds up on the inside of the screen. It disappears when the camera comes back to ambient temperature. My questions, is this bad and secondly is there a way to prevent it? Open it (which I'm rather reluctant to do, as going thru the mod was already difficult enough for me) and let it dry maybe?

Thanks

Yes its bad and you need to insulate your heat pipe and the electrically insulate the back of the sensor  pcb, people use glue from a hot glue gun sometimes.

Hello,

to be honest it is still in testing phase. I started off with putting the camera in a box (tried with a metal one and a plastic one), but turned out to be too heavy for my focuser, which can support up to 1.3kg. I use the usual components, heatsinks, fans and TEC-element. Let's say, it's still in a too premature stage to reveal it now; not that I don't want, I just don't want to look like a fool amid all the experienced astrophotographers here - looking at my username I hope you understand.

Kind  regards,
