What makes the Canon EOS 60Da special?
The "a" in the name literally stands for astrophotography. Canon modified the optical low-pass filter (OLPF) in front of the sensor so it transmits roughly three times more hydrogen-alpha (HΞ±) light at 656nm than a standard 60D. That's the deep red wavelength emitted by ionised hydrogen in emission nebulae β the kind of light that shows up beautifully in images of the Orion Nebula or the Rosette Nebula but gets blocked by the IR-cut filter in a normal camera body.
Compared to the standard Canon EOS 60D (which shares the same chassis, 18.1 MP sensor, articulating screen and 5.3 fps burst), the 60Da is identical in almost every specification except that one crucial filter change. In daylight, this modification shifts white balance slightly warm β so the 60Da is a dedicated astronomy tool rather than a do-everything camera. For pure night-sky work, the 60Da outperforms any unmodified body at the same price point when capturing emission nebulae.
Canon later revisited the concept with the full-frame Canon EOS Ra, which uses a similar HΞ±-modified filter on a mirrorless body. The Ra offers about four times the HΞ± transmission compared to a standard EOS R. The 60Da sits in a different class β APS-C, optical viewfinder, EF mount β but remains an accessible entry point into dedicated DSLR astrophotography without the cost of a full-frame mirrorless system.
For wide-field astrophotography, the Canon EF 24-70mm f/2.8L II USM or the Canon EF 50mm f/1.4 USM are popular choices. For deep-sky work on a tracking mount, longer focal lengths provide the reach to isolate nebulae.
