The Barnard Objects have fascinated professional and amateur astronomers for over 100 years. Barnard’s images were obtained with black and white photographic plates. Astronomical photographic plates have been replaced by digital imaging with CCD and CMOS chips. This book directly compares Barnards images from A Photographic Atlas of Selected Regions of the Milky Way with modern color images of the same regions and on the same scale. This book complements The Barnard Objects – Then and Now.
