Ccd Astrophotography: High-quality Imaging From... Page

Elias, an astrophotographer, used a cooled CCD sensor on his observatory telescope to capture stunning images of the Great Nebula in Orion, overcoming the limitations of earlier film and DSLR technology. By meticulously collecting raw data through long, guided exposures and processing it with dark and flat frames to remove noise, he produced a vibrant, detailed image of stellar birth that the human eye cannot see.
