Designed especially for photographers who want to capture galaxies far, far away the EOS 20Da camera delivers outstanding photos of the night sky. Most features of the EOS 20Da are shared with the standard EOS 20D camera but several important modifications have been made to optimize the camera’s astrophotography capabilities.

The EOS 20Da yields sharper and higher contrast images of various astronomical phenomena such as diffuse reddish nebulae because of a special, modified low-pass filter that is positioned in front of the EOS 20Da’s 8.2 Megapixel CMOS sensor,. The modification increases the transmission of light at the specific wavelength of 656nm, known as the Hydrogen Alpha line or Ha wavelength, by a factor of 2.5x compared to the standard EOS 20D.
