Peltier coolers have proven too inefficient to cool modern CPUs and have been relegated back to car seats and other traditional usages, until now. A company called PrimaLuce will send you a Nikon D5500 with a peltier cooler strapped to the back which will cool your camera during long exposures which reduces image noise. It will also prevent the camera from getting obnoxiously warm, a common complaint around the PCPer office. This particular camera is intended for capturing the night sky, the inclusion of a anti-dewing system is very welcome. Pop on over to Ars Technica to take a look.
"For €2,190 (£2,000/$2,400), the Italian company PrimaLuce will sell you a Nikon D5500 DSLR with a dual-Peltier cooler strapped to the back, called the Nikon D5500a Cooled. In addition to the cooler, the modified camera also switches out the standard low-pass filter in front of the sensor for something that is specially tuned to be more sensitive to astronomical wavelengths of light (specifically H-alpha deep red)."
