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 Astronomical photographic plates have been replaced by digital imaging with CCD and CMOS chips.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 .

Sequel to The Barnard Objects: Then and Now Detailed comparison of Barnard's original photographic plates and the modern complementary color images Features a guide for amateur astronomers interested in viewing and imaging the Barnard Objects

Dr. Tim Hunter is Professor Emeritus in the Department of Medical Imaging in the College of Medicine at the University of Arizona and was Head of the department 2008-2011. He has been an amateur astronomer since 1950 and owns the 3towers Observatory and the Grasslands Observatory. Dr. Hunter has been the President of the Tucson Amateur Astronomy Association, Inc. (TAAA) and a member of the TAAA since 1975. He was previously Chair of the Board of Trustees of the Planetary Science Institute (PSI). Since 1986, Dr. Hunter has been interested in the growing problem of light pollution. In 1987, he and Dr. David Crawford founded the International Dark-Sky Association, Inc. (IDA). IDA is a nonprofit corporation devoted to promoting quality outdoor lighting and combatting the effects of light pollution. Since 2007, Dr. Hunter has written a weekly "Sky Spy" column for the Caliente Section of the Arizona Daily Star. Asteroid 6398 is named Timhunter. James E. McGaha obtained a BS in management and physics from Georgia Tech University, an MA in management and psychology from Webster University, and a MS in Astronomy and Astrophysics from the University of Arizona. He is currently a retired United States Air Force pilot and is a skeptic lecturer. He is the Director of the Grasslands Observatory (www.3towers.com) and specializes in asteroid and comet astrometry and photometry. He has made over 2900 Minor Planet Electronic Circular (MPEC) publications of near-Earth objects (NEOs) and discovered 63 comets. He identified and performed photometry of optical afterglow of gamma ray burst 030329. He is a contributing author for Skeptical Inquirer magazine and is a scientific and technical consultant to the Committee for Skeptical Inquiry (CSI). He is a Fellow of the Royal Astronomical Society (RASC). Prof. Gerald Orin Dobek obtained two BS degrees in Mathematics, Trinity College and Ferris State University, a MSc Honours in Astronomy from the University of Western Sydney and a DSc in Astronomy and Astrophysics from James Cook University. Dr. Dobek is currently the Head of Sciences and Department Head of Astronomy at Northwestern Michigan College, where he teaches Astronomy. As a professional astronomer, he researches small amplitude variable stars using his private observatory at his home in Traverse City, Michigan. Jerry also continues to research dark nebulous material in the Milky Way. In 2011, he republished Edward Emerson Barnard's "A Photographic Atlas of Selected Regions of the Milky Way," adding updated information and a mosaic of the fifty plates contained within the Atlas. Jerry holds membership in numerous astronomy and science organizations: FRAS, AAS, AAAS, AAVSO, ASP and is a founding member of the IDA.
