Canon has introduced a version of the mirror EOS 60D digital camera for astrophotography, reports Engadget. The model is called 60Da.
Between the sensor and the lens at the 60Da is a low-pass filter, which transmits more radiation in the red spectral region. 60Da is three times more sensitive to radiation with a wavelength of 656.28 nm (the spectral line of H-alpha) than the 60D, says Canon. This allows the distinct images of nebulae and other astronomical objects.
60Da can be used for everyday photography, but due to the nature of color filters in the photographs would be more “warm” than the 60D.
Like the 60D, the new camera is equipped with a 18-megapixel CMOS-matrix format
