In his free time, Sean spent countless hours learning computer image processing techniques, as well as perfecting a few of his own. This attracted the attention of the editorial staff, and a few years later moved over to assistant editor, specializing in astrophotography and new-product coverage.
Rather than concentrating on one imaging discipline, Sean pursues a multitude of imaging projects, from deep exposures of faint galaxies, to capturing high-resolution records of the Sun, Moon, and planets with an ever-changing arsenal of cameras and telescopes. A self-described "gear head," he is constantly testing out or trading astronomy equipment.
