The Barnard Objects: Then and Now

巴納德天體已經吸引了專業和業餘天文學家一百多年。許多最初由E.E.巴納德在黑白照片上拍攝的天體現在每天都被數千張彩色天體攝影所捕捉。這本書講述了巴納德的故事，描述了他的生活和工作，以及從那時起天文學和天體攝影領域的轉變。

這些章節既有歷史又有科學，為讀者提供了對星雲科學的介紹，以及這個領域在幾十年來所取得的令人驚奇的發現；對巴納德等流行天文目錄的概述；以及從巴納德時代以來天文攝影的進步，從早期的底片到數碼攝影和芯片。此外，該書還提供了一個全面的指南，教你如何觀察和攝影這些天體。書中還提供了天文和攝影術語的詳細解釋和參考資料。還包括了巴納德天體位置的最新表格，讓你一睹E.E.巴納德原始目錄中缺失的二十五個天體。

這本引人入勝的參考書經過豐富的研究和插圖，將吸引各級天文學家對天文學、天體攝影以及過去一百年來它們的變化感興趣。

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.

Dr. Tim Hunter是亞利桑那大學醫學院醫學影像學系的名譽教授，並在2008年至2011年擔任該系主任。他自1950年以來一直是業餘天文學家，擁有3towers Observatory和Grasslands Observatory。Dr. Hunter曾擔任圖森業餘天文學協會（Tucson Amateur Astronomy Association, Inc.）的會長，並自1975年起成為該協會的成員。他曾擔任行星科學研究所（Planetary Science Institute）董事會主席。自1986年以來，Dr. Hunter對光污染問題越來越感興趣。在1987年，他與Dr. David Crawford共同創辦了國際黑暗天空協會（International Dark-Sky Association, Inc.）。IDA是一家致力於推廣優質室外照明和對抗光污染影響的非營利組織。自2007年以來，Dr. Hunter每週為亞利桑那每日星報（Arizona Daily Star）的Caliente版撰寫一個名為“Sky Spy”的專欄。小行星6398以他的名字命名。
