cooled

Ordinary cameras can be modified for astrophotography by introducing additional cooling for the sensor. CentralDS has one extreme way of keeping sensors chilly: it extracts sensors from cameras and moves them into their own external cooling module.

An Italian astrophotography company called PrismaLuceLab has launched a modded version of the Nikon D5500 DSLR. Called the "D5500a Cooled," the camera uses a special cooling system mounted on the back to chill the sensor and reduce noise during long-exposure photos.
