NGC 278 is an isolated spiral galaxy in the northern circumpolar constellation of Cassiopeia, near the southern constellation boundary with Andromeda. It lies at a distance of approximately 39 megalight-years from the Milky Way, giving it a physical scale of 190 ly (58 pc) per arcsecond. The galaxy was discovered on December 11, 1786 by German-born astronomer William Herschel. J. L. E. Dreyer described it as, "considerably bright, pretty large, round, 2 stars of 10th magnitude near".

NGC 84 is a star in the Andromeda constellation. It was recorded on November 14, 1884 by Guillaume Bigourdan. It is situated close to the Celestial equator, making it at least partly visible in the sky, from both hemispheres in certain times of the year. It is usually mistaken with PGC 1384.
NGC 398 is a lenticular galaxy located in the constellation Pisces. It was discovered on October 28, 1886 by Guillaume Bigourdan. It was described by Dreyer as "very faint, very small, stellar."
NGC 7010 is a massive elliptical galaxy located about 365 million light-years from Earth in the constellation Aquarius. NGC 7010 was discovered by astronomer John Herschel on August 6, 1823, and was later listed by French astronomer Guillaume Bigourdan as IC 5082.
NGC 6028 is a barred lenticular galaxy and a ring galaxy located about 200 million light-years away in the constellation Hercules. Ring galaxies such as NGC 6028 are also known as Hoag-type galaxies as they may have a resemblance to the prototype, Hoag's Object. NGC 6028 was discovered by astronomer William Herschel on March 14, 1784. It was then rediscovered by astronomer Guillaume Bigourdan on May 4, 1886.
NGC 6044 is a lenticular galaxy located about 465 million light-years away in the constellation Hercules. NGC 6044 was discovered by astronomer Lewis Swift on June 27, 1886. It was then rediscovered by astronomer Guillaume Bigourdan on June 8, 1888. NGC 6044 is a member of the Hercules Cluster.
NGC 4875 is a lenticular galaxy located about 350 million light-years away in the constellation Coma Berenices. NGC 4875 was discovered by astronomer Guillaume Bigourdan on May 16, 1885. The galaxy is a member of the Coma Cluster.
NGC 4876 is an elliptical galaxy located about 325 million light-years away in the constellation Coma Berenices. NGC 4876 was discovered by astronomer Guillaume Bigourdan on May 16, 1885. NGC 4876 is a member of the Coma Cluster.
NGC 3312 is a large and highly inclined spiral galaxy located about 194 million light-years away in the constellation Hydra. The galaxy was discovered by astronomer John Herschel on March 26, 1835. It was later rediscovered by astronomer Guillaume Bigourdan on February 26, 1887. NGC 3312 was later listed and equated with IC 629 because the two objects share essentially the same celestial coordinates. NGC 3312 is the largest spiral galaxy in the Hydra Cluster and is also classified as a LINER galaxy.
NGC 1259 is a lenticular galaxy located about 243 million light-years away in the constellation Perseus. The galaxy was discovered by astronomer Guillaume Bigourdan on October 21, 1884 and is a member of the Perseus Cluster.
NGC 1264 is a low-surface-brightness barred spiral galaxy located about 145 million light-years away in the constellation Perseus. The galaxy was discovered by astronomer Guillaume Bigourdan on October 19, 1884. NGC 1264 is a member of the Perseus Cluster.
NGC 1271 is a compact elliptical or lenticular galaxy located about 250 million light-years away in the constellation Perseus. The galaxy was discovered by astronomer Guillaume Bigourdan on November 14, 1884. NGC 1271 is a member of the Perseus Cluster and has a nuclear dust disk in its center. It also has an edge-on, intermediate-scale disk and has a central bulge. Like NGC 1277, NGC 1271 is a candidate "relic galaxy".
NGC 1278 is an elliptical galaxy located about 230 million light-years away in the constellation Perseus. NGC 1278 was discovered by astronomer Heinrich d'Arrest on February 14, 1863. It was then rediscovered by astronomer Guillaume Bigourdan on October 22, 1884 and was later listed as IC 1907. NGC 1278 is a member of the Perseus Cluster and is a low-luminosity AGN (LLAGN).
NGC 1282 is an elliptical galaxy located about 230 million light-years away in the constellation Perseus. It was discovered by astronomer Guillaume Bigourdan on October 23, 1884. NGC 1282 is a member of the Perseus Cluster.
NGC 1283 is an elliptical galaxy located about 250 million light-years away in the constellation Perseus. The galaxy was discovered by astronomer Guillaume Bigourdan on October 23, 1884 and is a member of the Perseus Cluster. It also contains an active galactic nucleus.
NGC 6054 is a barred lenticular galaxy located about 460 million light-years away in the constellation Hercules. It was discovered by astronomer Lewis Swift on June 27, 1886. It was then rediscovered by astronomer Guillaume Bigourdan on June 1, 1888. PGC 57073 is often misidentified as NGC 6054. NGC 6054 is a member of the Hercules Cluster.
