Thanks, do you screw the peltier to the camera back or use thermal epoxy or similar?

How do you control temperature?

[maro21]

Yes, the radiator has been screwed up to backplate with m4 screw .  I am going to install thermostat.

This does appear to be the cooling solution described by Martin Pyott on YouTube.

@maro21, thanks  for posting your work.

DIY cooling is awesome. I was talking about my DSLR cooling project on an astronomy discord and they were just laughing at me. It's an interesting way to learn things and get nice results it seems, rather than relying on companies to do things for you.

I have changed peltier for 2a with thermally paste.   I have noticed a problem with ice on filter . M46 only 15x30s ts65q.
