Camera makers Canon has announced the EOS 60Da DSLR, a modified version of its 60D exclusively designed for astrophotography.The Canon EOS 60Da succeeds the 20Da in the firm’s line-up and has a modified low pass filter that makes the camera more sensitive to hydrogen-alpha wavelengths of light. Ordinary IR filters are tuned for the human eye, but block out wavelengths that many astral objects emit light along — while the 60Da’s filter fixes this.
Elsewhere it looks to be the same 18-megapixel 60D, maintaining the normal ISO range of up to 6400,and 14-bit DIGIC 4 processing. On the back there is a 1,040k-dot resolution. And Time-Lapse shooting can be completed through EOS Utility or an optional Timer Remote Controller. Canon claims the screen is improved for stargazing, though at least on paper the 60Da keeps the same 3-inch size and 1.04 million dot resolution. The Canon EOS 60Da will be available this month for $1499.99, a $500 premium on the vanilla 60D, and the availability will be limited to “select authorised dealers.”
