Have you wanted to take pictures of far off galaxies, distant stars, or perhaps highly-detailed photos of the Moon? Well you can with the Canon 20Da dSLR. The camera is much the same as the Canon 20D, but with a few important modifications that make it highly suitable for astrophotography.

Have you wanted to take pictures of far off galaxies, distant stars, or
perhaps highly-detailed photos of the Moon? Well you can with the Canon
20Da dSLR. The camera is much the same as the Canon 20D, but with a few
important modifications that make it highly suitable for astrophotography.
The 20Da has a special low-pass filter in front of the image sensor that, according to Canon, "yields sharper and higher contrast images of various astronomical phenomena such as diffuse reddish nebulae." In addition, the Canon 20Da has a magnified live view mode on the LCD display - a feature not found on other dSLRs. This allows the photographer to get a better idea of the extent and composition of the photograph. The live view can also be hooked up to a TV or monitor for easier viewing.
The Canon 20Da also has improved noise reduction and an optimized CMOS control system. The camera's expanded ISO range is an impressive 50-3200. Of course, the camera can be mounted onto any telescope using a common T-mount, allowing you to take stunning photographs of the night sky.
