Langley was an assistant observer at Harvard College Observatory from 1865-66 (under the directorship of Joseph Winlock). Together with Austin, Peirce, Searle and Winlock he observed nebulae with the 15" f/18 Merz-refractor installed in June 1847 (see picture). The results are published in Ann. Harv. Obs. 13, 62 (1882). Langley discovered NGC 3355 in Hydra; alas, the object is lost.
