IC 923 is a lenticular galaxy located in Ursa Major. Its redshift is 0.069243 [1] which means the galaxy is 954 million light-years from Earth. [2] IC 923 has apparent dimensions of 0.50 x 0.2 arcmin, meaning it is approximately 139,000 light-years across. [3] IC 923 was discovered in June 1892, by Edward Emerson Barnard [4] [5] and is a member of galaxy group V1CG 588. [6]
NGC 4394 is a SBb barred spiral galaxy in the constellation Coma Berenices and is situated about 39.5 million light-years from Earth. It was discovered on 14 March 1784 by the German–British astronomer William Herschel. It is a presumed companion to the lenticular galaxy M85 / NGC 4382, which lies 8 arc minutes away. It is also a member of the Virgo Cluster.

NGC 4623 was discovered by astronomer William Herschel on April 13, 1784. NGC 4623 is a member of the Virgo Cluster.
NGC 4612 is a barred lenticular galaxy located about 57 million light-years away in the constellation of Virgo. NGC 4612 was discovered by astronomer William Herschel on January 23, 1784. The galaxy is a member of the Virgo Cluster.
NGC 4497 is a lenticular galaxy located about 60 million light-years away in the constellation Virgo. NGC 4497 was discovered by astronomer William Herschel on March 15, 1784. It was rediscovered by astronomer Arnold Schwassmann on November 8, 1900 and was listed as IC 3452. NGC 4497 is a member of the Virgo Cluster.
NGC 6040 is a spiral galaxy located about 550 million light-years away in the constellation Hercules. NGC 6040 was discovered by astronomer Édouard Stephan on June 27, 1870. NGC 6040 is interacting with the lenticular galaxy PGC 56942. As a result of this interaction, NGC 6040's southern spiral arm has been warped in the direction toward PGC 56942. NGC 6040 and PGC 56942 are both members of the Hercules Cluster.

IC 4026 is a lenticular galaxy located in Coma Berenices. It is located 315 million light-years away from the Solar System and has an approximate diameter of 70,000 light-years which is less the size of the Milky Way. IC 4026 was discovered on May 11, 1896, by astronomer Hermann Kobold and is a member of the Coma Cluster. It has a surface brightness of 11.99 mag/arcsecs meaning it is a high surface brightness galaxy.
