The 60Da has a modified infrared filter as well as a sensor that has been adjusted to reduce noise over long exposures while increasing its sensitivity to hydrogen alpha (sometimes known as H-alpha). There's plenty of H-alpha floating around in space even though our eyes -- and most traditional digital camera sensors can't see it. It usually plays a pretty pivotal role in those awesome images of the sun we've been seeing lately that depict the wild solar storms and flares. The 60Da's APS-C sensor is roughly three times more sensitive to H-alpha with some help from the modified infrared filter. The final result is a 20-percent increase in transmittance of the hydrogen alpha line.
Since H-alpha is a biproduct of hydrogen atoms (this specific kind occurs when a hydrogen electron drops an energy level) it tends to have the most dramatic visual effect in nebulas rich in that element. The visual spectrum line that's created has a wavelength of 656.28nm, which falls into the realm of reds, which is part of the reason you see so many striking space images in that shade.

Normally this wouldn't be of any intrigue to me however the one portion that piqued my ATS fancy enough to where I felt this article was post worthy was this camera's "specially modified IR filter" and "a sensor that's been altered for the specifics of taking photos of space".
Being that this camera is for the most part ($500 USD), fairly affordable, as compared to having to purchase one's own Hubble Telescope ($1.5 billion USD). That and the Nibiru followers seem to think that it can only be filmed or captured within the IR spectrum, perhaps now we will be able to get some real photos...right?

It should only be a matter of time now before we will see some verifiable photographic proof posted on ATS of the illusive Brown Dwarf Star that is creeping about our solar system.edit on 4/3/2012 by UberL33t because: (no reason given)
The EOS 60Da will only be available via select authorized dealers. It is set to sell for $1,499 without a lens and will be available for purchase this month.
It comes with a price tag about $500 higher than an equivalent non-space-focused camera,

I mis-read the original article that points to the article in the OP, my mistake...

It was on the front page of the Popular Science website and the "Read More" article takes you to the link in the OP.

Some amateurs, myself included, enjoy imaging in infrared.
Please tell us the details of what camera you use and how you shoot in IR.
Is your camera modified or factory set up for infra red?
Sounds really nice,I am not taking the micky,I am genuinely interested.
Terrestrial Infra red is cool enough,but I imagine it has certain benefits when used on the stars.
Indeed, I use it to observe stars not normally visible in normal visible light.

Wow,you modified the camera yourself?
That is hardcore!
Great results too.
Are those images of the Orion nebula single shots or composites?
What shutter speed did you use?

For single shots they look amazing bud.
Totally cool !
I sussed out your avatar was the ISS,but to have captured it with the last shuttle docked is beyond awesome IMO.
Must be very tricky to photograph ,as it moves fast.
I would be proud of that photo forever if I had taken it.
Looking forward to your other Orion nebula images.

Wow.
I simply do not have a drool bucket big enough...
Those shots are unquantifiable in their amount of awesomeness.
I hope you don't mind I copied them so I can zoom in.
