Canon EOS 60DA The first astrophotography-specialized DSLR since the 2004-vintage Canon EOS 20Da, the 60Da shares most of the features of the 60D, but with one key differences that will put a smile on any stargazer"s face. The Canon EOS 60Da features increased IR sensitivity for astrophotography (IR cut filter is modified to achieve a hydrogen-alpha (Ha) light (656nm) transparency approximately three times higher than the EOS 60D and other digital cameras) allowing crisp, clear images of reddish, diffuse nebulae. To capture the full range of colors given off by diffuse nebulae in the sky, the EOS 60Da features a specially tailored infrared blocking filter that allows the light normally blocked by a typical DSLR"s filter to be captured by the camera"s sensor. This means that the reddish hydrogen-alpha (Ha) light (656nm) gasses unseen by a normal DSLR are captured brightly and clearly on the EOS 60Da. With its modified infrared blocking filter, the EOS 60Da captures approximately 3x the hydrogen-alpha (Ha) rays than the EOS 60D, resulting in astrophotography that is sharper, clearer and more accurate. Along with the the Canon EOS 60Da a Remote Controller Adapter RA-E3, which allows compatibility with the optional Timer Remote Controller TC-80N3 for accurate control of long exposures and automatic shooting of repetitive shots with the interval timer is being bundled with the camera.
