Galaxies NGC 2726, NGC 2742 and NGC 2768
History
The three galaxies NGC 2726, NGC 2742 and NGC 2768 have been discovered by William Herschel on 19 March 1790. NGC 2726 he listed as II 834 and noted: «Pretty faint, pretty small, irregular figure, easily resolvable.» NGC 2742 he listed as I 249 and noted: «Considerably bright, extended, near parallel, easily resolvable, brighter in the middle, 4' long, 2' broad. I supose, with a higher power and longer attention, the stars would become visible.» NGC 2768 he listed as I 250 and noted: «Very bright, considerably large, little extended, large bright nucleus in the middle.» [465]
