It's literally the coolest DSLR astrophotography accessory to come along in years. This insulated, thermoelectrically cooled chamber for select Canon DSLRs chills the camera's imaging sensor, significantly reducing troublesome thermal noise in your astrophotos. When you're imaging the night sky in warm or hot weather, especially, such noise can wreak havoc on deep-sky images. Now, here's an affordable solution. Unlike many specialized astronomical CCD cameras, DSLRs do not have an internal cooling system. The Orion DSLR Camera Cooler acts as an external Peltier cooling system, which lowers the temperature inside the sealed chamber up to -43F (-24C) from ambient. And it works fast, achieving a temperature delta of -30F or more in just 30 minutes. This noise reduction allows longer exposures and less work in post-processing, resulting in smoother, more highly resolved, better images. Unlike direct-cooling Peltier installations that permanently alter your camera (and void your manufacturer's warranty), the DSLR Cooler requires no camera modification. The DSLR Camera Cooler is compatible only with select Canon EOS cameras widely used by astrophotographers: 1100D (T3), 550D (T2i), 500D (T1i), 1000D (XS), 450D (XSi), 400D (XTi), and 350D (XT). The Orion DSLR Cooler runs on external 12V power and draws 4 amps, so we recommend using a marine-type battery of at least 30 amp-hours or AC power via the optional AC-to-DC power adapter. A DC auto-lighter cable is included.
