John "Jack" Borden Newton (born 13 August 1942, Winnipeg, Manitoba) is a Canadian astronomer, best known for his publications and images in amateur astrophotography. Newton was 13 years old when he took his first astrophotograph, of the planet Saturn. He pioneered "cold camera" astrophotography, chilling a film camera with dry ice, allowing for substantially longer exposures on film to get detail out of very dim and distant celestial objects. In 1991 Newton became the first amateur astrophotographer to make full color CCD images of celestial objects using a Santa Barbara Instruments Group ST-4 camera, making a full color CCD image of M57, the "Ring Nebula" and M27, the "Dumbbell Nebula". He took three separate black and white images, each taken with a separate filter in red, blue, and green, which were later combined in software that was being developed for amateur astrophotography by Richard Berry, then editor of Astronomy magazine. Berry published the first combined color CCD image of M27 as his magazine's cover in February, 1992. More information...
