Note from the Atlas regarding Dark Object listings

In his article in the Astrophysical Journal for January, 1919 ( 49 , 1-23) Professor Barnard gave a list of 182 dark objects in the sky. Three of the objects in that list have been omitted here, viz., Nos. 52, 131 a , and 172, because by inadvertence the same object had been listed twice.  Mr. Barnard had begun a second list, most of the objects for which he had himself selected.  Their positions were determined by Miss Calvert.  It seemed best to begin the second list with No. 201; accordingly, there are no objects having the numbers from 176 to 200.


To retrieve a Dark Object listing, type any number between:

 1 - 51, including 44a
53 - 171, including 83a, 84a, 117a, and 119a
173 - 175
201 - 370
