NGC 68 is alenticular galaxy,[5] and the central member of theNGC 68 group, in the constellationAndromeda. The galaxy was discovered on September 11, 1784, byWilliam Herschel, who observed the NGC 68 group as a single object and described it as "extremely faint, large, 3 or 4 stars plus nebulosity".[3] As such, his reported location is between NGC 68, NGC 70, and NGC 71. By the timeDreyer looked at the galaxies to add to the NGC catalog, however, he was able to tell that the single galaxy observed by Herschel was in fact 3 adjacent galaxies, and cataloged them asNGC 68,NGC 70, andNGC 71.
