Peltier cooled Nikon D5500 DSLR perfect for astrophotography

PrismaLuceLab, an Italian astrophotography specialist, has launched a modified version of the Nikon D5500 DSLR – dubbed the D5500a Cooled camera, which uses a special peltier-based cooling system located at the back to cool the sensor and reduce noise while taking long exposure photos.

According to a PetaPixel report, PrismaLuceLab CEO Filippo Bradaschia said that a cooled CCD camera has better performance in astrophotography compared to traditional DSLRs. Also, Bradaschia claimed that the D5500a Cooled can be used without a computer unlike other CCD astro cameras.

The cooling system occupies the LCD screen space on the camera's back while the LCD screen is kept in a flipped out position.

Also, due to the cooling system, the temperature inside the camera is reduced, lessening the noise too. The cooling system displays the current temperature of the sensor, speed of the cooling fan, desired temperature, and intensity of the anti-dewing system.

Meanwhile, touch buttons allows users to adjust these parameters to their desired values and control the integrated shutter.

Powered by a 12V adapter, the cooling system also has a 9V output that can power the DSLR through the battery compartment with an included adapter. Through this, users can power the system with a single 12V adapter and without batteries.

To increase sensitivity in astrophotography, the filter in front of the sensor is replaced with another that is specially designed for the D5500a Cooled.

The Nikon D5500a Cooled camera is now available through PrismaLuceLab for about ~US$2,422.
