With the advent of amateur-level astronomical-quality CCD cameras, Jack was one of the first to yeild high-quality results in making digital images that rivaled those produced through some of the largest professional telescopes in the world. In 1990 he made the first amateur tri-color CCD images of celestial objects. With the deep imaging capabilities of the modern CCD cameras with their low noise, the images reach beyond the old benchmarks like the Palomar Sky Survey and are now referenced using the Carnegie Atlas premiering the work on photographic plates over the last 60 years from the 100" telescope at Mt. Wilson and the 200" Hale Telescope at Mt. Palomar.
