Picked this up on PetaPixel site, hope they don't move it to links and stuff because it is specific to this site!
I will put the link in my next post here....it should keep it here!

Peltier cells, if they go wonky, can act like a reverse heat exchanger, causing disastrous condensation on electronics. They fell out of favor with PC modders for this reason.

"The Nikon D5500a Cooled is now available through PrismaLuceLab for €2,190 (~$2,422). By comparison, the standard D5500 costs $650."

If you do the math, for $3072 to try and make a DSLR do something it was not intended for, you could have a choice of many top Astrophotography Cameras that are built for the task. (Including proven TEC to cool their sensors to sub-zero C temperatures.)

Sorry, NO SALE.

This is a lot of $ (or even Euros) for a D5500. While I do appreciate the work it takes to build this, have to agree that a purpose-built camera would probably do a better job at a lower cost.

The article seems to address the exact problems you mentioned as been monitored and displayed so as not to ruin your unit should you purchase one!
I note that most everybody here so far have a thumbs down on this....mostly because of price.
I first thought that you could clip this cooling unit to any camera with a swing out LCD screen.....but it turns out they did some extensive work on the sensor too, in essence turning the camera chosen into a special purpose camera....bummer!
I just posted this because it is specifically geared for astro-photography, I have no horse in the race, just an interest in stuff !

While it may be a good concept, there are many better choices for Astrophotography specific cameras. I've rigged up my DSLR and taken some sky pictures with it, but the images came out so wide field that my objective was nearly lost in the star field. I did like the images overall, but my intended targets were tiny.
So I prefer to use my astro specific camera, which is cooled, and takes a much more object specific image.
It is very hard for me to perceive anyone actually investing in such an overpriced adaption when there are so many purpose specific options floating around out there.

Some images to compare the objective sizes when used for Deep Space... (NOT great pictures, just examples. As taken.)
