NGC 53 is a ringed barred spiral galaxy in the constellation Tucana. It was discovered by John Herschel on 15 September 1836. He described it as "very faint, small, extended". The galaxy is approximately 120,000 light-years across, making it about as large as the Milky Way.

NGC 67 is an elliptical galaxy located in the constellation Andromeda that was discovered on October 7, 1855, by R. J. Mitchell, who described it as "extremely faint, very small, round". The galaxy belongs to the NGC 68 group, which also contains the galaxies NGC 68, NGC 69, NGC 70, NGC 71, NGC 72, and possibly NGC 74.

<span class="mw-page-title-main">NGC 68</span> Galaxy in the constellation Andromeda

NGC 68 is a lenticular galaxy, and the central member of the NGC 68 group, in the constellation Andromeda. The galaxy was discovered on September 11, 1784, by William Herschel, who observed the NGC 68 group as a single object and described it as "extremely faint, large, 3 or 4 stars plus nebulosity". As such, his reported location is between NGC 68, NGC 70, and NGC 71. By the time Dreyer 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 as NGC 68, NGC 70, and NGC 71.

<span class="mw-page-title-main">NGC 68 group</span> Galaxy group in the constellation Andromeda

VV 166, sometimes also called the NGC 70 galaxy group or Arp 113, is a cluster of galaxies in Andromeda. The main group was discovered in 1784 by William Herschel, who listed the galaxies as a single object. Later, in the 1880s, John Louis Emil Dreyer managed to discern some of the galaxies in this region and cataloged them. The prominent elliptical galaxy in the region, NGC 68, is probably not a member of the group.

NGC 70 is a spiral galaxy located in the constellation Andromeda. It was discovered on October 7, 1855, by R. J. Mitchell and was also observed on December 19, 1897 by Guillaume Bigourdan from France who described it as "extremely faint, very small, round, between 2 faint stars".

<span class="mw-page-title-main">NGC 71</span> Galaxy in the constellation Andromeda

NGC 71 is an elliptical galaxy located in the constellation Andromeda. It is in the NGC 68 group. The galaxy was discovered by R. J. Mitchell in 1855, and observed in 1865 by Heinrich d'Arrest, who described it as "extremely faint, very small, round". The galaxy is about 110,000-130,000 light years across, making it just slightly larger than the Milky Way. The galaxy is the second largest in the NGC 68 group, after spiral galaxy NGC 70.
