IC 10 is an irregular galaxy in the constellation Cassiopeia. It was discovered by Lewis Swift in 1887 and in 1935 Nicholas Mayall became the first to suggest that the object is extragalactic. Edwin Hubble suspected it might belong to the Local Group of galaxies, but its status remained uncertain for decades. The radial velocity of IC 10 was measured in 1962, and it was found to be approaching the Milky Way at approximately 350 km/s, strengthening the evidence for its membership in the Local Group. Its membership in the group was finally confirmed in 1996 by direct measurements of its distance based on observations of Cepheids; most estimates place the galaxy 2–3 million light years from Earth, with some estimates ranging from 1.5–4.5 million light years. Despite its closeness, the galaxy is rather difficult to study because it lies near the plane of the Milky Way and is therefore heavily obscured by interstellar matter.
IC 1011 is a barred spiral galaxy with apparent magnitude of 14.7, and with a redshift of z=0.02564 (SIMBAD) or 0.025703 (NASA), yielding a distance of 100 to 120 megaparsecs. Its light has taken 349.5 million years to travel to Earth. IC 1011's calculated age is approximately 12.95 billion years. The IC designation comes from the Index Catalogue.
IC 4271 is a spiral galaxy located some 800 million light-years away in the Canes Venatici constellation. It is 130,000 light-years in diameter.

It hosts a Seyfert type 2 nucleus, containing an acceleration disc around its supermassive black hole which releases large amounts of radiation, hence its bright appearance. IC 4271 appears to be interacting with its smaller neighboring galaxy, PGC 3096774.

IC 2759 is a small type E elliptical galaxy located in the constellation of Leo. It is located 350 million light-years away from the Solar System and was discovered on April 24, 1897, by Guillaume Bigourdan. Sometimes IC 2759 is confused with the spiral galaxy, PGC 34882 which is located south of the galaxy.

IC 3622 also known as PGC 3793395, is a large barred spiral galaxy located in constellation Coma Berenices. It is located 980 million light-years from the Solar System and has a diameter of 175,000 light-years. IC 3622 was discovered by Royal Harwood Frost on May 7, 1904.
IC 4539 is a type SABb intermediate spiral galaxy located in Corona Borealis. Its redshift is 0.061307, which corresponds IC 4539 to be 845 million light-years from Earth. It has an apparent dimension of 0.40 x 0.4 arcmin, meaning the galaxy is about 95,000 light-years across. IC 4539 was discovered by Stephane Javelle on June 23, 1903, who found it "as faint, small, round with a very brighter middle."
IC 923 is a lenticular galaxy located in Ursa Major. Its redshift is 0.069243 which means the galaxy is 954 million light-years from Earth. IC 923 has apparent dimensions of 0.50 x 0.2 arcmin, meaning it is approximately 139,000 light-years across. IC 923 was discovered in June 1892, by Edward Emerson Barnard and is a member of galaxy group V1CG 588.
IC 1327 is lenticular galaxy of type S0-a, located in the constellation Aquila. Its redshift is 0.032386, which corresponds IC 1327 to be located 445 million light-years from Earth. It has an apparent dimension of 0.90 x 0.8 arcmin, meaning the galaxy is 117,000 light-years across. IC 1327 was discovered on August 10, 1890, by Sherburne Wesley Burnham.
