R. J. Mitchell

Mitchell found 95 NGC-objects and 3 IC-objects; 88 NGC- and all IC-objects were new. The known ones are all due to W. Herschel. Mitchell was an assitant of Lord Rosse using his 72" reflector at Birr Castle. All objects but one (NGC 7387) can be found in: Parsons W., On the Construction of Specula of Six-feet Aperture; and a selection from the Observations of nebulae made with them, Phil. Trans. 151, 681-745 (1861). N 7387 is included in: Parsons L., Observations of Nebulae and Clusters of Stars 1848-1878, Scient. Trans. Roy. Dublin Soc. Vol. II, 1-178 (1880)
