Canon's new DSLR has been tweaked to help it capture all the beautiful stuff out there in space
Like the EOS 20Da that came before it, Canon's EOS 60Da shares many of its features with its non-astronomical sibling. They have made a few tweaks, however, to facilitate taking photos of the heavens.
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.
