Not that I know of. CCDs don't generate a lot of heat, so the cooling only has to be relative to ambient, which peltier can do fine. I'd worry more about things

Not that I know of. CCDs don't generate a lot of heat, so the cooling only has to be relative to ambient, which peltier can do fine. I'd worry more about things like thermal shock when pouring liquid nitrogen over a CCD than the gains in Signal-to-Noise ratio. Although, there are scientific instruments that get cooled way further into super conducting state.
