At Harvard Safford discovered 2 NGC objects in Orion on March 19, 1863 using the 15" f/18 Merz refractor installed in June 1847. George Phillips Bond (director from 1859-1865) published the observations (among others by Bond, Coolidge and Tuttle) in AN #1453 (1863). NGC 2189 (No. 7a, 7b in Bond's list, also HN 25/26) is described as "two clusters", but only the two reference stars can be seen. The other finding, NGC 2198 (No. 8, HN 27), is quite similar: instead of a cluster only the two reference stars are present. HN stands for "Harvard Nebula", given in Pickering, E. C., Detection of Nebulae by Photography, Ann. Harv. Obs. 18, 113-117 (1890).

At Dearborn Observatory, Sufford found 106 objects between 1866 and 1868 with the 18.5" refractor. They were noticed too late by Dreyer to enter the NGC, because they were published 1887 in the Annual Report of the Board of Directors of the Chicago Astronomical Society, together with the Report of the Director of Dearborn Observatory for 1885 and 1886. 47 of them, classified as "new" by Dreyer, were listed in an Appendix to the NGC (with their Safford-No.), but Dreyer put them completely into the IC I. 3 objects were found by his assistant Skinner. All but three are real deep sky objects. IC 1148 = NGC 6020 is a curious case,as the IC designation must be seen the primary!
