|A "Pilgrims Progress" Talk Given at the Cotuit Library|
As Harry covered his experiences with astrophotography, he explained the basics of how back in the day, simple exposures of the night sky could capture brilliant colors from deep-sky objects such as diffused nebula. Harry also touched on such methods of the (now antiquated) technique of "hyper-sensitizing" print or slide film to the newly conventional methods for astrophotography utilizing digital and CCD cameras.
