Pickering found 17 NGC- and 2 IC-objects; 15 NGC- and both IC-objects were new. All NGC-objects (exept one, the open cluster IC 2581 in Carina) are planetary nebulae, found by visual spectroscopy at the 15" refractor of Harvard College Observatory. The 2 ICs were discovered on a plate made at Arequipa of the Eta Carinae region. Dreyer credits Pickering for 15 other IC objects: IC 418 in Lepus, IC 420, 421, 423, 424, 426, 427, 428, 430, 431, 432, 434, 435 in Orion, IC 1266 in Ara, and IC 1297 in Crater. All were found by Williamina Fleming, with one exception (IC 434), which was detected much earlier by William Herschel.
