This box draws 10Amps of current, which is a lot and therefore requires a heavy-duty 240/12v power adapter with pretty thick cables, or straight from a car battery in the field.
Yesterday I got a reading inside the box well below freezing on a warm summers day, this goes even lower in winter months of course.
The inside of my Nikon D7000 gets to nearly +40C uncooled with repeated long exposures and I was getting down to -2C with it inside the box running on a september night with a corresponding reduction in sensor noise.
The results will vary, depending on the camera, ambient conditions, consistant power supply, pauses between exposures, length of exposures, overall session duration etc.
Apart from my D7000, i mounted a Canon 6d inside without any adjustments to the base screw or the front opening. I am happy to adapt the box to suit any DSLR, i just need a dimensioned manufacturers drawing to proceed.
The original Martin Pyott design works well for a flip-screen DSLR with a single cooler that places a plate of copper directly to the rear of the sensor. Not so with non-flipscreen, hence the need for extra cooler to penetrate the camera body, this has the added benefit of even weight distribution.
