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)."

Meh. For TRUE noise
Meh. For TRUE noise suppression, one should use liquid nitrogen!
The thing that comes immediately to mind for that setup, is astronomical photos, so you can capture the messiest of messier objects, the andromeda galaxy, the orion nebula (a naked eye object, did you know? It’s that fuzzy blob hanging from the “belt” of Orion.), or the ring nebula in lyra.
Good call, as that is exactly
Good call, as that is exactly what it is intended for. Hope to see more space porn soon!

Old news, there is whole industry of modified cameras for astrophotography serving to niche of astrophotographers. Looks like you guys are living under rock to not know about this astrophotography tools.

Over such long exposures, I’d expect the fans to introduce some vibration.
I have a 6″ apochromatic
I have a 6″ apochromatic telescope that would be perfect for that camera… if it hadn’t been dropped, and the lens shocked, so that it’s now severely astigmatic.
It’s the precursor to the current Starfire model lineup from Astro-Physics, and it’s damage makes me weep bitter and everlasting tears of frustrated rage against fate!
If any of you are optics experts who think they can repair a shocked Christen triplet apochromatic lens, let me know, and I’ll send it to you for the cost of shipping… which will be enormous for a 40lb scope with 40lb equatorial mount and 40lb oak tripod…
