Miss Fleming found 54 IC objects; 50 were new. She inspected plates taken with Harvard's Bache telescope (8" f/5.5 refractor), equipped with an objective prism. It was first used at Harvard College Observatory and transported to Arequipa in spring 1889 (see e.g. PASP 4, 58 (1892)). The objects in Orion were found on a plate, taken at Harvard. Among them is the famous Horsehead Nebula (it is very doubtfult that William Herschel has seen it in 1786). The other objects, mostly planetary nebulae, were discovered from objective prism plates taken at Arequipa. Some objects were credited by Dreyer to Pickering.
