Welcome to the world of extreme camera modding

A lot of us modify our gear to make things better suit the tasks we need them to perform. Sometimes we do it just to speed up workflow a little. Rarely, however, are the modifications quite as extreme as the Nikon D5500a from Primaluce Lab. Based on a Nikon D5500 this camera has had the stock CMOS sensor switched out for a CCD. They also added a pretty hardcore cooling system.

The reason for this is astrophotography. It’s a pretty common fact that CCD sensors tend to do much better than CMOS sensors for this type of photography. But, the big problem with CCD sensors for long exposures is the build up of noise over time due to heat. I used to see this in my old Nikon D100 bodies which used CCD sensors. Anything exposures over about 10-15 seconds were packed full of noise.

The cooler pretty much triples the depth of the camera, before adding a lens. It kinda makes seeing through the viewfinder a little tricky. I don’t imagine this will be too much of an issue, though, as it’s not really designed to be used handheld anyway.

Astrophotography is typically long to very long exposures. So, it’s going to be mounted on a tripod, or a rig that counters the rotation of the earth to keep a constant fix on the skies. The live view screen will likely be much easier to use than an optical viewfinder ever could be anyway.

It’s an interesting, if slightly unusual, Frankenstein of technology. One would think that it would be easier to simply build your own camera housing to go around the sensor and other technology. Modifying a commercial camera to such an extreme amount can’t have been an easy task. But, the D5500 comes with a lot of cool hardware already built in, with a nice compact design.

Along with switching out the sensor, they also swapped out the filter that sits over the sensor, to help increase its sensitivity to red light. This helps for astrophotography where much of the light is towards the red end of the spectrum.

An “anti-dewing system” has also been added to help reduce humidity build up on long exposures. With a cooler that can keep the sensor at a chilly 27°C below ambient, you can see why this was required.

You can find out more about the D5500A over on the Primaluce Lab website. It costs €2,190 and is available to order now. For comparison, a stock Nikon D5500 costs around $897.

Now, if only we can get Sony to do something similar with their cameras to let them shoot 4K video for more than 10 minutes.

I can’t ever imagine myself needing a camera like this, but I’m curious what the astrophotographers think. Is this crazy awesome? Or is it a bit too over-engineered, and you’re just fine with your Nikon D810A? At a little over half the price of the D810A, is it even a little bit tempting? Have you done any extreme modding with your camera? What did you do? Give us your thoughts and show off your hacks and astrophotography in the comments.
