The Missing Barnard Objects
by Tim Hunter and Gerald Dobek
The 1927 A Photographic Atlas of Selected Regions of the Milky Way started with Barnard’s initial 1919 list of 182 dark nebulae, which he numbered from 1 to 175 with seven subcategories of 44a, 67a, 83a, 84a, 117a, 119a, and 131a. Frost and Calvert in compiling objects for the 1927 Atlas added further objects as numbers 201 to 370. They provided no Barnard Object listings for numbers 176-200 even though it was apparent from Barnard’s notes there were several other dark nebulae he wished to include in his list but did not get around to officially numbering them or otherwise documenting them.
Frost and Calvert omitted objects numbered 52, 131a, and 172 from Barnard’s original 1919 listing feeling these were erroneous duplicates. Dobek in his 2011 reproduction of Barnard’s 1927 Atlas added those objects back in documenting their existence from Barnard’s notes. Dobek also documented 24 dark nebulae as good candidates for the missing Barnard Objects 176-199 in addition to adding an interesting dark region he calls the Trident as Barnard 200. These were first presented in our book The Barnard Objects-Then and Now (Springer-Nature 2023) from which these annotated charts and images of Barnard Objects 186-200 are mainly derived.
